Telebucaramanga and the Fixed-Line Annuity Under Bucaramanga's Converg

Summary

The article treats Telebucaramanga as a historical fixed-access position rather than a current independent retail story.
It follows ownership absorption, local pricing, CRC evidence, network records and the economics of keeping Santander customers in a bundle.
The thesis strengthens if the old footprint shows fibre upgrades, lower churn and better customer experience under the larger owner.

A Bucaramanga Bill Shows Why the Old Network Still Has a Price

The economic case for TELEBUCARAMANGA S.A. E.S.P. can be seen in a modest recurring household or small-business bill, not in a nostalgic local brand. Movistar Colombia's current consumer page lists a 500 Mbps home internet plan at COP 84,900 per month, and bundles the same fixed connection with mobile service at COP 119,900 per month (https://www.movistar.com.co/hogar/planes-internet-hogar). A local Bucaramanga challenger, Innovation Telecomunicaciones, advertises 200 Mbps internet at COP 44,900 and 900 Mbps at COP 99,900, with internet-plus-TV bundles from COP 64,900 (https://innovationtelecomunicaciones.com/). The Commission for Communications Regulation, or CRC, put the national average monthly revenue per fixed access at COP 94,915 in June 2025 (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-presenta-nuevas-cifras-sobre-servicios-fijos-usan-hogares). That is the price zone in which an old fixed operator either becomes an annuity or becomes stranded plant.

Telebucaramanga's value is therefore not that Bucaramanga lacks competition. It clearly has competition from national operators, local fibre sellers, mobile substitution and increasingly satellite or fixed-wireless options. Its value is that a wired access network, a customer file, an address-by-address service memory and an old billing relationship can still be turned into broadband, TV, mobile and business-service revenue after the copper-era identity has disappeared. In a city where a family decides whether COP 84,900 is acceptable for a fixed line and a small shop decides whether it needs static-quality connectivity for payments, video, security cameras and cloud accounting, the historical local network remains a monetisable control surface.

That is why the name TELEBUCARAMANGA S.A. E.S.P. should not be read as an independent retail story in 2026. The public filings show a regional telephone company absorbed into Colombia Telecomunicaciones, later pulled into the broader Tigo-Movistar consolidation. The investment judgment is narrower and more durable: how much of a regional fixed-line annuity survives when the brand, corporate perimeter and network planning are nationalised. The answer is that the local operator lost its standalone face, but the assets that made the name relevant still have economic use if they reduce churn, support fibre migration, anchor converged bundles and give the new owner a deeper position in Santander's most important urban market.

The Name Now Points to a Network Inheritance, Not a Standalone Retail Brand

The first discipline is to separate the legal and commercial layers. Telefónica Colombia describes its local activity under the Movistar commercial brand as mobile telephony and connectivity, broadband, fibre to the home, pay television, fixed telephony and digital solutions for small, medium and large companies (https://www.telefonica.co/en/about-us/telefonica-colombia/). Its 2020 responsible-management report says Metrotel and Telebucaramanga were operating under the Movistar trademark from November 2018, with administrative work carried out by Colombia Telecomunicaciones, and then describes the 2020 merger authorisation and registration process (https://descubre.movistar.co/informe-de-gestion-responsable-2020/en/movistar-colombia.html). The company that a Bucaramanga customer sees is therefore Movistar, and after 2026 it sits inside Millicom's Colombian consolidation.

Local reporting captured the commercial moment. Vanguardia reported in November 2018 that Telefónica Movistar had made the Telebucaramanga integration official under the message "Ahora somos Movistar", bringing 328,000 Telebucaramanga customers into Movistar processes and lifting the combined Movistar-branded base mentioned in that report to 884,000 customers (https://www.vanguardia.com/economia/local/2018/11/09/telefonica-movistar-concluyo-su-fusion-con-telebucaramanga/). Semana framed the same integration with Metrotel and Telebucaramanga as a move that made Movistar a larger integrated operator in Barranquilla and Bucaramanga, managing 611,000 clients in those cities (https://www.semana.com/telebucaramanga-y-metrotel-se-integran-a-telefonica/264105/). The numbers differ because they refer to different combinations and scopes, but the strategic message is consistent: a local fixed operator was not being abandoned; it was being folded into a national converged machine.

The formal merger confirmed that conclusion. Colombia Telecomunicaciones' issuer report for the 2019 bondholder process explained that Coltel would absorb Telebucaramanga and Metrotel after the required corporate and regulatory approvals, transferring their assets and liabilities in block and dissolving the absorbed companies without liquidation (https://www.telefonica.co/wp-content/uploads/sites/4/2023/02/Informe-del-Emisor-1-1.pdf). The 29 May 2020 relevant-information notice says the Superintendencia Financiera authorised the merger by absorption, that public deed No. 769 was granted on 27 May 2020, and that registration in the Bogota Chamber of Commerce occurred on 28 May 2020; the same notice reported post-merger Coltel assets of COP 14.012 trillion and liabilities of COP 9.079 trillion based on March 2020 financial statements (https://www.telefonica.co/wp-content/uploads/sites/4/2023/02/20200529-Perfeccionamiento-fusion-CT-Metrotel-y-Telebucaramanga.pdf).

The result is a business that remains visible through inherited network records and regional customer economics more than through a public-facing corporate identity. Coltel's 2024 consolidated financial statements still recount that in 2018 Colombia Telecomunicaciones registered its group situation with Empresa de Telecomunicaciones de Bucaramanga S.A. E.S.P. and Metropolitana de Comunicaciones S.A. E.S.P., and that in 2020 it absorbed Metrotel and Telebucaramanga (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). That is not a sentimental footnote. It explains why an old Bucaramanga name can still appear in internet-number registries even while customer acquisition, product design and capital allocation are controlled at the Coltel or Millicom level.

The Fixed-Line Base Became Valuable Because Bucaramanga Was Already Wired

Telebucaramanga's original importance was local density. A fixed access business is expensive because it must pass streets before it can sell services, and it must keep technicians, ducts, poles, cabinets, customer-premises equipment and repair workflows close to the customer. Once built, however, the same path can carry voice, broadband, IPTV, enterprise access and backhaul. That is why a municipal or regional fixed operator can retain value after mobile has won the attention market. Mobile owns the pocket; fixed access owns high-capacity, high-usage hours in the home and workplace.

The national data show why the old local plant needed reinvention rather than simple preservation. The CRC's 2024 industry report says Colombian telecom operational revenues reached COP 30.3 trillion in 2024, with fixed internet, mobile internet and carrier service together accounting for 65% of sector revenue, while fixed telephony revenue fell 11.8% and fixed lines fell 7.6% (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-publica-reporte-industria-2024-un-panorama-completo-sectores-tic). A March 2025 CRC release, using second-quarter 2024 data, put fixed telephony accesses at 7.02 million after a 7.2% year-on-year decline, while fibre accesses rose 20% to 3.63 million (https://www.crcom.gov.co/es/noticias/comunicado-prensa/accesos-internet-fijo-con-fibra-optica-crecieron-en-2024-alcanzando-363). This is the core shift: voice shrinks, but the right-of-way and customer installation can be upgraded into broadband value.

Bucaramanga makes that shift more attractive than a thin rural footprint. The metro area has households, apartment buildings, SMEs, universities, health providers, restaurants and professional services that can buy stable fixed connectivity. Vanguardia's 2018 report said Telefónica planned COP 71 billion of investment between 2018 and 2019 to strengthen coverage, infrastructure and telephony network in the integration, while also noting that a business-to-business innovation centre would use the old Telebucaramanga building to serve more than 80,000 Santander micro, small, medium and large enterprises in digital transformation processes (https://www.vanguardia.com/economia/local/2018/11/09/telefonica-movistar-concluyo-su-fusion-con-telebucaramanga/). Even if that centre is not the present operating story, the passage shows the strategic logic at the time: the local fixed asset was a platform for regional enterprise relationships, not just a declining telephone switch.

This matters because fixed-line economics are path-dependent. A challenger can advertise a cheap plan, but must still build or lease a local access path, support installations, finance customer equipment and wait for payback. The incumbent that inherited the local plant carries legacy costs, but also inherits known addresses, network records, crews and a customer base that can be repriced into fibre. Movistar said in November 2025 that its fibre customers reached 1.59 million in 96 Colombian cities and represented 99.7% of the company's broadband base, after an eight-year migration from copper to fibre (https://www.telefonica.co/la-fibra-ya-conecta-a-todos-los-clientes-de-internet-fijo-de-movistar-colombia/). That does not isolate Bucaramanga, but it shows the national strategy into which Telebucaramanga's old local access base was absorbed: copper voice converted into fibre broadband, then used to hold the household or SME relationship.

Coltel Bought Operating Simplicity When It Absorbed the Local Carrier

The 2020 absorption was not merely an accounting tidying exercise. For a telecom group, legal simplification can lower friction in procurement, financing, vendor negotiations, tax administration, network planning and product launch. A separate regional company may preserve local identity, but it can complicate national bundles, common systems and capital allocation. Coltel's issuer report stated plainly that the merger meant Coltel would absorb Telebucaramanga and Metrotel, with the absorbed companies transferring assets and liabilities and dissolving without liquidation (https://www.telefonica.co/wp-content/uploads/sites/4/2023/02/Informe-del-Emisor-1-1.pdf). That is the form of a simplification move.

The operating reason is visible in the service stack. Coltel's corporate object in its 2024 financial statements covers local, extended local and long-distance fixed telephony, mobile services, carrier services, satellite services, television, wireless technologies, hosting, data centre services, private and public network operations, content, applications and other information-technology and communications services (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). A local fixed operator with one city identity cannot efficiently price that full catalogue alone. It becomes more valuable when its access network is used as a local entry point into the wider catalogue.

The customer economics also reward consolidation. A standalone fixed voice line can be cancelled when a household shifts to mobile calling. A broadband line with mobile, streaming, TV app and support features can be harder to dislodge if the bill is competitive and the installation works. Movistar's consumer page breaks the 500 Mbps internet-plus-mobile bundle into a fixed internet component and a mobile component, illustrating how the bill is engineered around multiple services rather than one line (https://www.movistar.com.co/hogar/planes-internet-hogar). Its business-fibre page advertises fibre-plus-mobile bundles for companies, including 700 Mbps and up-to-1,000 Mbps business combinations with mobile plans and fixed-service features such as static IP mapping in some offers (https://www.movistar.com.co/empresas/soluciones-fijas/fibra-optica). A regional fixed base becomes more resilient when it can be attached to those bundles.

Coltel's 2024 financials show why operating simplicity is necessary. The group reported COP 6.682 trillion in operating income, COP 5.131 trillion in operating costs and expenses, COP 1.057 trillion of depreciation and amortisation, COP 700 billion of net financial expense and a net loss of COP 469.9 billion for 2024; the statement is expressed in thousands of Colombian pesos, so the headline figures are trillion-level at operating scale (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). A company with that cost base cannot afford many small local exceptions. The annuity value of Bucaramanga must be harvested through shared systems, national procurement and common network planning, not through a preserved local bureaucracy.

The Network Records Still Show a Bucaramanga-Centered Eyeball System

The most concrete surviving evidence of Telebucaramanga's technical identity is AS22368. LACNIC RDAP records the autonomous system as active, directly allocated, registered on 18 September 2001, and associated with TELEBUCARAMANGA S.A. E.S.P.; the registrant address shown in the RDAP record is on Calle 36 in Bucaramanga, while administrative and technical contact details point to a Telefonica hostmaster function in Bogota (https://rdap.lacnic.net/rdap/autnum/AS22368). This is exactly what one would expect after a local carrier is absorbed: the registry name can remain local, while operational administration is integrated into the national group.

The routing view reinforces the point. RIPEstat's AS overview identifies AS22368 as "AS22368 - TELEBUCARAMANGA S.A. E.S.P." and marks it as announced on 4 July 2026 (https://stat.ripe.net/data/as-overview/data.json?resource=AS22368). RIPEstat's routing-status endpoint, queried for the same date, reported 132 IPv4 prefixes, 62,720 announced IPv4 addresses, zero IPv6 prefixes and one observed neighbour, with full IPv4 visibility across 325 of 325 RIS peers and no IPv6 visibility (https://stat.ripe.net/data/routing-status/data.json?resource=AS22368). BGP.tools similarly describes AS22368 as an active LACNIC network, classifies it as an eyeball network, lists 132 originated IPv4 prefixes and no IPv6 prefixes, and shows the upstream as AS3816, Colombia Telecomunicaciones S.A. ESP BIC (https://bgp.tools/as/22368). IPinfo also lists the registered name as TELEBUCARAMANGA S.A. E.S.P., with 62,720 IPv4 addresses, zero IPv6 addresses, LACNIC registry status, and important routers in Bucaramanga and Floridablanca (https://ipinfo.io/AS22368).

These details should be read as infrastructure evidence, not as proof of a separate commercial company. The AS name tells us that Telebucaramanga's historical internet-number footprint is still routable and visible. The upstream relationship into Coltel tells us that the traffic economics are now inside the national operator. The absence of visible IPv6 in these public routing views tells us something more cautious: this legacy footprint appears IPv4-heavy in public BGP observation, which is common for older access networks but may require additional inspection before drawing conclusions about customer-facing IPv6 readiness.

The value of the AS is not the number itself. It is the customer traffic behind it. IPinfo describes the activity pattern as consumer ISP-like and shows a geography concentrated in Colombia, with router locations in Bucaramanga and Floridablanca (https://ipinfo.io/AS22368). A consumer or SME eyeball network is a recurring demand source for upstream capacity, customer support, content delivery, security handling and local fault repair. If it churns, the operator loses not just voice minutes but high-usage fixed broadband hours. If it holds, the operator has a base to upsell fibre, TV app, mobile lines and business services.

The routing footprint also explains why network operations cannot be judged only by brand visibility. A customer may never see the Telebucaramanga name on a bill, yet the old AS name can remain in public routing data for years after a merger. That persistence is not unusual; renumbering customers or retiring address space can be operationally risky and commercially pointless if the network is working. For an owner such as Millicom, the question is whether the legacy footprint can be rationalised into the combined Colombian architecture without service disruption, not whether the old name disappears from every technical record.

Fibre Competition Changes the Price, Not the Need for a Local Last Mile

The most obvious challenge to the fixed-line annuity is price compression. A household in Bucaramanga can compare Movistar's COP 84,900 500 Mbps standalone plan with local fibre offers such as Innovation's COP 44,900 200 Mbps and COP 99,900 900 Mbps plans (https://www.movistar.com.co/hogar/planes-internet-hogar and https://innovationtelecomunicaciones.com/). Price comparison alone, however, understates the incumbent's advantage and risk. The incumbent's advantage is coverage, brand support, repair capacity and bundling. The risk is that once a local challenger has installed fibre in a neighbourhood, the customer can use the incumbent's price as a ceiling rather than a default.

The Colombian fixed market is now a fibre market. CRC reported that by second-quarter 2025 fixed internet reached 9.69 million accesses, fibre accounted for 52% of accesses, cable for 41.2%, and the average contracted download speed reached 429 Mbps (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-presenta-nuevas-cifras-sobre-servicios-fijos-usan-hogares). Its 2024 industry report put fibre at 47.9% of fixed internet accesses and 4.4 million connections during 2024, with average download speed up 69.5% to 382 Mbps and upload speed up 92.9% to 234 Mbps (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-publica-reporte-industria-2024-un-panorama-completo-sectores-tic). MinTIC's fourth-quarter 2024 release said Colombia had 9.09 million fixed internet accesses and a national average fixed download speed above 227 Mbps at year-end 2024 (https://www.mintic.gov.co/portal/inicio/Sala-de-prensa/Noticias/400791:Al-cierre-del-cuarto-trimestre-de-2024-Colombia-registro-un-total-de-9-09-millones-de-accesos-fijos-a-Internet).

These numbers imply that Bucaramanga customers increasingly buy capacity, not a historic telephone company. The old local operator can survive only if the access path is fast enough and the service experience is good enough to justify a monthly bill. The annuity is no longer copper voice; it is the household's willingness to keep one fixed broadband subscription as the base layer for work, entertainment, payments, study, security and family connectivity. That willingness can be strong, but it is not unconditional.

The incumbent's defence is convergence. Movistar's home page and product pages emphasize fixed internet, mobile, television and app-based services in one sales environment (https://www.movistar.com.co/hogar). Its small-business page similarly packages fibre with mobile, support and fixed service characteristics (https://www.movistar.com.co/pymes/soluciones-fibra). If a Bucaramanga SME needs broadband, a mobile plan, installation support and a supplier with a national customer-service apparatus, the national operator can sell a lower-risk procurement decision than a very small provider. If the SME only wants the cheapest fast pipe, the challenger has room to win.

The price signal is therefore double-edged. Low local offers show that the market is no longer captive, but they also validate the service category. A family comparing 200, 500 or 900 Mbps plans is not deciding whether fixed broadband matters; it is deciding which operator gets the recurring line in the household budget. That turns every existing address relationship into a contested but valuable option. If the old Telebucaramanga footprint lets the owner defend a home with one field visit, a modem swap or a bundle discount, the retention cost can be lower than acquiring the same address later. If the operator waits until the customer has already moved, the same address may require promotional pricing, new installation work and a weaker margin. The annuity is thus not passive rent. It is an installed-base advantage that must be refreshed before a rival resets the customer's expectations.

The annuity therefore depends on the mix of customers. Apartment households with high streaming use may churn for price. SMEs that process card payments, run WhatsApp sales, maintain cloud inventory or rely on video surveillance may pay for stability and support. Public institutions and larger businesses may need more formal contracts, static addresses, service levels or integration with mobile fleets. Telebucaramanga's old local base matters because it gives the national owner a known installed footprint from which to segment those customers, rather than forcing it to acquire every address from scratch.

The Cost Base Is Heavy Before the First Customer Opens a Browser

The fixed-access business is attractive only after one accepts how capital-heavy it is. Coltel's 2024 consolidated balance sheet reported total assets of COP 14.460 trillion, including COP 4.311 trillion of property, plant and equipment, COP 1.417 trillion of right-of-use assets, COP 1.205 trillion of intangibles and COP 1.218 trillion of goodwill; total liabilities were COP 10.974 trillion (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). Those figures are not Telebucaramanga-specific, but they define the financial container into which Telebucaramanga was absorbed. The local annuity is valuable only if it contributes to a national network whose asset base is already enormous.

The cash-flow picture is similarly disciplined. In 2024 Coltel recorded COP 488 billion of payments for investments in plant, equipment and intangibles, down from COP 815 billion in 2023, and COP 430 billion of net cash used in investing activities (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). Depreciation and amortisation of COP 1.057 trillion sits between operating cash generation and bottom-line profit. That means a Bucaramanga fixed customer cannot be valued only by the monthly bill. The relevant question is whether the customer uses already-deployed plant, requires incremental drop fibre or equipment, needs frequent truck rolls, takes a discounted bundle, and stays long enough to repay acquisition and installation costs.

This is where an inherited operator differs from a pure challenger. A challenger may spend less on legacy systems, but it must still win permits, lease or build access, finance installations and persuade each building to switch. The incumbent carries old costs, yet it may already know which addresses are serviceable and which customers are likely to buy a higher-value bundle. That information advantage is mundane, but in fixed broadband it can be the difference between profitable infill and expensive overbuild.

The company's own accounting notes make that customer-life logic explicit. Coltel's financial statements say prepaid expenses include equipment used to provide television, broadband and basic-line services delivered to customers, amortised over the shorter of average customer life and useful life of the installed element; customer-contract fulfilment costs mainly include equipment installation services for television, broadband and basic line, also amortised over that shorter period (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). In plain terms, the operator spends before it earns. It places equipment, connects the customer, supports the line and then waits for monthly bills to turn that work into margin.

The upstream and wholesale layer adds another cost exposure. Coltel's notes describe obligations related to network capacity, last-mile rental, national interconnection traffic and roaming, and refer to greater network-capacity services for fixed clients in 2024 (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). For a legacy Bucaramanga network, that means local access is only part of the economics. The customer also consumes upstream transit, content delivery, backbone capacity, support systems, power and customer care. When speed expectations rise from tens of megabits to hundreds, the access annuity must fund more than the final drop.

This is why scale became central. The same financial statements describe the mobile access network sharing project with Colombia Movil, including Unired Colombia S.A.S. and a temporary union for spectrum, with the stated aim of more efficient management of existing networks and deployment of new technologies such as 5G, while the companies would continue competing commercially (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). That project is mobile-focused, but it shows the same corporate instinct that absorbed Telebucaramanga: reduce duplicated infrastructure where possible, preserve market-facing competition where required, and use scale to finance network obligations.

Customer Dependency Is Household Cash Flow and SME Continuity

A fixed operator's social importance is easy to overstate in generic language, but the dependency is concrete. A Bucaramanga family may use the fixed connection for a parent working remotely, a child studying, a television app, gaming, medical appointments, bank authentication and family communication. A small retailer may use it for card payments, supplier orders, security cameras and accounting. The customer rarely thinks in terms of network architecture. The customer thinks in terms of whether the bill is affordable and whether the connection fails at the wrong time.

National indicators show that fixed access is still far from universal. The CRC reported that in second-quarter 2025 fixed internet penetration reached 47.6 residential accesses per 100 households, equivalent to 9.69 million accesses (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-presenta-nuevas-cifras-sobre-servicios-fijos-usan-hogares). In its 2024 industry report, the CRC said that 94 of every 100 people had mobile internet, while 46 of every 100 households had fixed internet (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-publica-reporte-industria-2024-un-panorama-completo-sectores-tic). The difference matters: mobile is broad, but fixed broadband is still a household asset with uneven reach and higher capacity.

Affordability is the hinge. MinTIC reported that one gigabyte of mobile data under subscription cost an average COP 1,745 at the end of 2024, while the country had more than 49 million mobile internet accesses (https://www.mintic.gov.co/portal/inicio/Sala-de-prensa/Noticias/400791:Al-cierre-del-cuarto-trimestre-de-2024-Colombia-registro-un-total-de-9-09-millones-de-accesos-fijos-a-Internet). That cheap mobile data can substitute for light tasks, but it is not the same product as a stable home fibre line used by several people and devices. The fixed operator's recurring value lies in that gap: mobile may be the universal connection, but fixed access is still the capacity layer for households and workplaces that can pay.

The customer relationship is also defensive. CRC's 2025 fixed-services release said 44.7% of fixed accesses were individual services, 37.8% were triple-play packages and 17.5% were double-play packages, with internet-and-telephony the most representative double-play combination at more than 1.04 million accesses (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-presenta-nuevas-cifras-sobre-servicios-fijos-usan-hogares). For Telebucaramanga's inherited base, the best customers are not necessarily the highest-speed customers. They are the customers whose fixed connection is woven into multiple services and therefore less likely to churn on a small price difference.

SMEs add another layer. Movistar's business-fibre offer includes up to 1,000 Mbps business combinations, mobile lines, support features and fixed-service components such as static IP mapping in certain plans (https://www.movistar.com.co/empresas/soluciones-fijas/fibra-optica). Those details matter because SME broadband is not only a speed product. It is a procurement risk decision. A shop, clinic or professional office may choose a provider that can solve failures, provide predictable invoices and support future bundles. Telebucaramanga's inherited local recognition, even under Movistar, can help if customers remember the operator as the fixed-line incumbent. It can hurt if customers remember slow repairs or legacy bureaucracy. The annuity is therefore earned each month, not guaranteed by history.

Regulation Turns a Local Access Network Into a National Convergence Asset

Colombia's telecom rules shape the value of Telebucaramanga's inheritance. Coltel's 2024 financial statements state that the company is subject to Law 1341 of 2009 and the applicable public-service company regime, and they identify licenses, authorisations, spectrum, coverage obligations, quality levels and regulatory sanctions as business risks (https://www.telefonica.co/wp-content/uploads/sites/4/2025/03/EEFF-Coltel-Consolidado-2024.pdf). Even a local fixed access network sits inside national rules on user protection, service quality, reporting, competition and interconnection.

That regulatory setting has two effects. First, it limits the freedom to treat a legacy network simply as an asset to milk. Service continuity, user rights and quality obligations impose costs. Second, it makes scale more valuable because reporting, legal, compliance, spectrum and competition obligations are easier to manage inside a larger operator. Telebucaramanga's absorption into Coltel and then Coltel's consolidation into Millicom should be read partly through that lens. A regional fixed carrier may have local goodwill; a national operator has the compliance machinery and capital access required by a regulated converged market.

Regulation also affects competition. Coltel's relevant-information page says the Superintendencia de Industria y Comercio approved the requested business integration between Colombia Telecomunicaciones and Colombia Movil with conditions through Resolution No. 94169 of 13 November 2025 (https://www.telefonica.co/accionistas-e-inversionistas/informacion-relevante-2/). That came after earlier approvals and network-sharing moves. The same page records a February 2024 framework agreement with Colombia Movil for a single mobile access network through an independent company and shared spectrum rights (https://www.telefonica.co/accionistas-e-inversionistas/informacion-relevante-2/). While those entries focus on mobile and corporate control, they set the competitive backdrop for fixed assets too: regulators are allowing consolidation, but not without conditions.

For Bucaramanga, the practical implication is that the old fixed network becomes part of a larger bargaining position. Millicom is not buying only customers; it is buying a way to compete with Claro across mobile, fixed, TV and business services. Telebucaramanga's local access base supports that strategy if it strengthens Millicom's fixed presence in a metropolitan market. It becomes less attractive if regulatory conditions force divestitures, if customer remedies reduce pricing freedom, or if integration absorbs management attention without improving service quality.

The Postdata fixed-internet dashboard also shows how granular public measurement has become. It presents quarterly information on fixed internet revenue, accesses and speeds reported by telecom providers under CRC reporting formats T.1.1 and T.1.3 from Resolution CRC 5050 of 2016 (https://www.postdata.gov.co/informacion-internet-fijo). That means fixed-access performance is increasingly observable. If the inherited Bucaramanga network underperforms in speed, complaints or penetration, the market and regulator can see the broader symptoms. If it performs well, the owner can use it as evidence that consolidation is funding better connectivity.

Millicom Bought More Than Mobile Scale When It Took Coltel

The final ownership shift changes the strategic reader. In March 2025, Millicom and Telefonica announced a definitive agreement for Millicom to acquire Telefonica's 67.5% stake in Coltel, subject to closing conditions including regulatory approvals; the announcement also said Millicom would offer to buy the remaining 32.5% held by La Nacion and other investors at the same price per share (https://www.globenewswire.com/news-release/2025/03/12/3041832/0/en/millicom-tigo-and-telefonica-sign-definitive-sale-purchase-agreement-in-colombia.html). Coltel later reported that Telefonica Hispanoamerica accepted Millicom Colombia Holding's tender offer for 2.301 billion shares, representing 67.5% of shares, and that Millicom acquired control on 6 February 2026 (https://www.telefonica.co/accionistas-e-inversionistas/informacion-relevante-2/).

Millicom then completed the second step. On 27 April 2026 it announced that it had acquired the remaining 32.5% equity stake in Coltel formerly held by La Nacion, presenting the purchase as the final step in strategic consolidation after the February 2026 tender offer (https://www.globenewswire.com/news-release/2026/4/27/3282044/0/en/millicom-tigo-strengthens-its-position-in-colombia-following-the-successful-acquisition-of-the-government-stake-in-coltel.html). Mobile Time reported the state-stake adjudication at 1.108 billion shares priced at COP 772.38 per share, for a total above COP 856.002 billion, with Millicom as the only prequalified interested investor in that second stage (https://mobiletime.la/noticias/24/04/2026/millicom-compra-acciones-movistar/). TeleSemana later framed Millicom as owner of 100% of Tigo Colombia and reported that the 32.5% state stake cost COP 856.002702394.98 billion, about USD 237 million, with total Colombian consolidation spending above USD 1 billion when related transactions are included (https://www.telesemana.com/blog/2026/04/29/millicom-se-queda-con-el-100-de-tigo-colombia-pago-mas-por-el-325-del-estado-que-por-el-control-de-telefonica/).

The public headline is mobile consolidation, but Telebucaramanga's residual value is fixed convergence. Millicom's April 2026 release says the acquisition improves scale and investment capacity, supports nationwide 5G deployment, service quality and digital inclusion, and places the transaction in a landscape where traditional operators compete with global digital platforms, satellite providers and other connectivity players (https://www.globenewswire.com/news-release/2026/4/27/3282044/0/en/millicom-tigo-strengthens-its-position-in-colombia-following-the-successful-acquisition-of-the-government-stake-in-coltel.html). Those statements are corporate positioning, but they are still useful. A fixed customer in Bucaramanga helps justify a converged operator because fixed access adds household depth that mobile-only scale cannot provide.

Millicom also brings its own regional fixed logic. Its March 2025 release says the group provides fixed and mobile services in Latin America, including pay TV, high-speed data, voice, business-to-business cloud and security services, and that at year-end 2024 it had more than 46 million customers and a fibre-cable footprint of about 14 million homes passed (https://www.globenewswire.com/news-release/2025/03/12/3041832/0/en/millicom-tigo-and-telefonica-sign-definitive-sale-purchase-agreement-in-colombia.html). Its April 2026 release updates that to approximately 52 million customers and a fibre-cable footprint over 14 million homes passed at year-end 2025, including the Honduras joint venture (https://www.globenewswire.com/news-release/2026/4/27/3282044/0/en/millicom-tigo-strengthens-its-position-in-colombia-following-the-successful-acquisition-of-the-government-stake-in-coltel.html). Telebucaramanga's old access base is small against that footprint, but it fits the operating model: fixed plant, mobile cross-sell, TV and digital services layered over local access.

The transaction price also changes how the inherited Bucaramanga base should be valued. If Millicom paid for Coltel only to gain mobile subscribers, fixed assets would be a side benefit. But the public announcements repeatedly frame the deal around investment capacity, converged services and nationwide connectivity, while the former Movistar operation itself reported 3.5 million fixed customers and 1.59 million fibre customers in the first nine months of 2025 (https://www.telefonica.co/la-fibra-ya-conecta-a-todos-los-clientes-de-internet-fijo-de-movistar-colombia/). In that context, a legacy metro fixed base is not a rounding error. It is part of the reason the combined operator can spread marketing, field service, backbone, customer-care and product-development costs over more revenue lines. The question is whether Millicom can lift the revenue per local address without creating the political and customer backlash that often follows telecom consolidation. That requires visible service improvement, not only a new shareholder.

The risk is that consolidation can become financial engineering without local service improvement. If Millicom uses scale only to cut duplicative costs, customers may see fewer alternatives and little quality gain. If it uses scale to improve fibre coverage, support and business-grade offers, the old Telebucaramanga base becomes a useful regional platform. The difference will show up in churn, speeds, complaint levels, SME uptake and whether Bucaramanga customers see credible alternatives at the same addresses.

The Residual Rent Is Real, But It Is Not a Monopoly

Telebucaramanga's residual rent has three components. The first is address-level presence: ducts, access paths, cabinets, customer premises and local repair knowledge that lower the cost of serving an existing neighbourhood compared with greenfield entry. The second is customer memory: the incumbent can approach households and SMEs with an existing service relationship, even if the bill now says Movistar or, over time, Tigo-Movistar. The third is network-number continuity: AS22368 and its IPv4 space remain announced and visible, giving the operator a technical base that supports customer traffic under the historical name (https://rdap.lacnic.net/rdap/autnum/AS22368 and https://stat.ripe.net/data/routing-status/data.json?resource=AS22368).

None of these components is absolute. Address-level presence decays if local challengers overbuild with cleaner fibre and better service. Customer memory decays if support is poor or pricing is uncompetitive. IPv4 resources remain useful, but they are not a substitute for modern access quality, IPv6 readiness, network resilience or customer trust. The public routing data show an active IPv4-heavy network with one observed neighbour and upstream into Coltel; they do not prove customer satisfaction or competitive strength (https://bgp.tools/as/22368 and https://ipinfo.io/AS22368).

The strongest argument for the annuity is that fixed internet is now the growth engine inside services that used to be anchored by voice and TV. CRC's 2025 fixed-services release says fixed-service revenue grew 6% year on year in second-quarter 2025, driven mainly by fixed internet, while closed TV and fixed telephony revenues declined 7.6% and 15.6% respectively (https://www.crcom.gov.co/es/noticias/comunicado-prensa/crc-presenta-nuevas-cifras-sobre-servicios-fijos-usan-hogares). If Bucaramanga customers can be migrated and retained on fibre, the old operator's local footprint remains relevant. If they remain tied to declining fixed voice or low-margin TV, the annuity erodes.

The strongest argument against the annuity is that consumers increasingly understand speed and price. Innovation's public prices show that a local entrant can talk to Bucaramanga customers with simple, low-friction offers (https://innovationtelecomunicaciones.com/). Other local and national providers can do the same. A historical network does not protect an operator if a customer can get cheaper symmetric fibre and competent support. The old fixed incumbent must therefore offer either better reliability, better bundle value, broader coverage, stronger SME capability or easier service recovery. Without those advantages, the annuity becomes a melting ice cube.

The best reading is conditional. Telebucaramanga is not valuable because it is old; it is valuable because it is old in a market where the last mile is still expensive, recurring demand is still high, and Millicom needs fixed depth to compete as a converged operator. It is vulnerable because the same market is full of fibre price competition, regulatory scrutiny and customers who no longer owe loyalty to a local telephone company. The annuity exists, but it must be defended with investment and service quality.

The Facts That Would Break or Strengthen the Fixed-Line Thesis

Several future facts would change this judgment. The first is address-level fibre performance in Bucaramanga and Floridablanca. If Millicom can show rising fibre penetration, lower fault rates, faster installation, lower churn and improved customer satisfaction in the old Telebucaramanga footprint, the local annuity is stronger than the registry record alone suggests. If customers leave for local fibre providers despite the larger owner's bundles, the annuity is weaker.

The second is the treatment of AS22368 and the inherited IPv4 footprint. If the owner keeps AS22368 stable while improving routing resilience, modernising customer access and adding visible IPv6 support, the old technical base remains a useful operating asset. If the network is slowly renumbered, retired or hidden inside a broader Coltel or Tigo architecture, that would not necessarily destroy customer value, but it would reduce the evidentiary importance of Telebucaramanga as a distinct technical footprint. Public data as of July 2026 show AS22368 still active and IPv4-visible through LACNIC, RIPEstat, BGP.tools and IPinfo (https://rdap.lacnic.net/rdap/autnum/AS22368, https://stat.ripe.net/data/as-overview/data.json?resource=AS22368, https://bgp.tools/as/22368, and https://ipinfo.io/AS22368).

The third is integration discipline after Millicom's 2026 control. A successful integration would preserve customer-facing continuity while improving procurement, backbone, product packaging, field operations and support. A poor integration would create billing confusion, support delays or price increases that make local challengers more attractive. Millicom's stated rationale is scale, investment capacity and service quality in a competitive market that includes satellite and digital-platform pressure (https://www.globenewswire.com/news-release/2026/4/27/3282044/0/en/millicom-tigo-strengthens-its-position-in-colombia-following-the-successful-acquisition-of-the-government-stake-in-coltel.html). The market will test whether that statement becomes better service at Bucaramanga addresses.

The fourth is regulation. If the SIC's conditions on the Coltel-Colombia Movil integration limit pricing freedom, require remedies that affect local fixed offers, or intensify scrutiny of converged bundles, the fixed annuity becomes more regulated and less purely commercial (https://www.telefonica.co/accionistas-e-inversionistas/informacion-relevante-2/). If regulators allow the enlarged operator to use scale while preserving open competition, the inherited fixed base could be a healthy counterweight to Claro rather than a source of local market power.

The fifth is the SME mix. A household-only base is more price-sensitive. A base with SMEs, public-sector users, clinics, universities and professional services can support higher-value contracts, static addressing, business support, cybersecurity, cloud and managed services. Movistar's business-fibre offers show the product direction; the unresolved question is how much of that demand can be won and retained in Santander through the old local access base (https://www.movistar.com.co/empresas/soluciones-fijas/fibra-optica).

The final judgment is therefore measured. TELEBUCARAMANGA S.A. E.S.P. is no longer the company a Bucaramanga household chooses by name. It is a historical fixed-access position inside a national operator that, as of 2026, sits in Millicom's consolidated Colombian platform. The old local identity lost autonomy, but the economic substance did not vanish. In a converged Colombia, a recurring fixed broadband bill in Bucaramanga can still be a valuable annuity if the owner keeps the network fast, the support credible and the bundle priced close enough to the local alternatives that customers stay.
