The old Digi name didn't vanish; it was absorbed

Treating DiGi Telecommunications Sdn. Bhd. as an independent Malaysian mobile operator today would be a mistake. A more accurate reading is that the directory entry reflects a historical operating company and a network-resource layer within the CelcomDigi group. The old DiGi name persists in the corporate structure, APNIC records, autonomous system evidence, and residual operational labels. The brand, investor narrative, main website, strategic control, and market story now belong to CelcomDigi Berhad.

This distinction matters because the Celcom-Digi merger did more than change a name. It altered the resource-allocation logic of the Malaysian mobile market. CelcomDigi now enjoys scale, channel breadth, a larger customer base, and a major synergy program. Simultaneously, the Malaysian Communications and Multimedia Commission imposed spectrum‑return remedies, wholesale terms for MVNOs, and a market structure where Digital Nasional Berhad’s wholesale 5G network limits even the largest operator’s freedom. The central question is therefore not whether CelcomDigi is large. It is. The question is to what extent that size is free.

The public corporate trail is clear. Digi.Com Berhad became CelcomDigi Berhad in 2023 after the Celcom-Digi combination. CelcomDigi’s 2023 Annual Report lists DiGi Telecommunications Sdn. Bhd. as a wholly‑owned subsidiary within the enlarged group. The current trading identity is CelcomDigi, presented viacelcomdigi.com, where the group describes itself as Malaysia’s largest mobile network operator and markets mobile, broadband, enterprise and digital services. The old DiGi registration is therefore not wrong. It is incomplete if not linked to CelcomDigi.

The network‑resource trail makes the story more interesting. APNIC registries continue to show AS10081 / DIGI‑MY as associated with DiGi Telecommunications Sdn. Bhd., while contacts and abuse reporting point back to CelcomDigi Telecommunications Sdn. Bhd. PeeringDB records for AS4818 describe CelcomDigi and reference the combined Celcom and Digi legacy. APNIC’s AS‑SET material ties AS4818, AS10081 and AS10030 into the same broader routing context. This is the normal residue of a telecom merger: brands and investor pages move first; legal and registry surfaces move more slowly; network engineering moves with the greatest caution.

The merger created scale — then regulation took some of it back

The Celcom‑Digi combination was the decisive event. Axiata, Telenor and Digi agreed the deal in 2021, regulatory clearance came in 2022 and completion followed later that year. The resulting business combined Celcom’s Axiata‑backed network and customer base with Digi’s Telenor‑backed operations. Axiata and Telenor each retained roughly one‑third of the merged listed company, creating a joint‑control setting rather than a simple takeover by one party.

The merger gave CelcomDigi a larger customer base, wider distribution, stronger procurement leverage, more scope to rationalise overlapping assets, and a clearer path to cost savings. CelcomDigi’s performance reports point to significant cumulative integration benefits: hundreds of millions of ringgit of P&L savings, meaningful capex avoidance, and a targeted steady‑state annual savings run‑rate. The economic logic is classic telecom consolidation. Two radio networks, two retail systems, two support stacks and two investment plans are progressively compressed into one national operating machine.

But Malaysia did not let that scale arrive unconditionally. Merger clearance required the combined operator to return 70 MHz of spectrum across the 1800 MHz, 2100 MHz and 2600 MHz bands, together with wholesale and MVNO safeguards. That remedy is the key to understanding CelcomDigi. Regulators accepted the industrial logic of the deal, but they did not want the new operator locking up too much scarce spectrum inside a single group. Scale was permitted, but constrained.

The spectrum story therefore became dynamic rather than cumulative. CelcomDigi holds meaningful low‑band and mid‑band resources, including stakes in 900 MHz, 1800 MHz, 2100 MHz and 2600 MHz, referenced in public and company materials. It subsequently accepted new 1800 MHz and 2600 MHz assignments with upfront and annual fee obligations. But the spectrum‑return history means that every future renewal or re‑assignment must be read through the lens of the regulator’s market structure. CelcomDigi is spectrum‑rich relative to smaller challengers, but not unconstrained.

DNB changes the economics of 5G

Malaysia’s 5G model is the largest structural constraint. Digital Nasional Berhad was created to build a national wholesale 5G network and avoid duplicative roll‑out. DNB’s model shifted the economics of early 5G from a logic where each mobile operator builds its own full national 5G network to a wholesale‑access system. Only once nationwide coverage hits policy‑set thresholds would Malaysia move to a dual‑network model.

For CelcomDigi, this creates a paradox. As the largest mobile operator, it would normally want to use 5G network ownership to differentiate on speed, coverage, enterprise private networks and capital‑deployment scale. Under DNB, 5G starts as a wholesale input with long‑term access obligations, service‑level expectations and financial commitments. CelcomDigi can compete on commercial proposition, device offers, customer care, in‑building experience, 4G/5G handover, enterprise bundles and brand trust. It does not fully control the underlying national 5G asset the way an unconstrained incumbent would.

This changes the profit mechanics. In a traditional self‑build model, cost pressure appears mainly as capex and depreciation. Under DNB, 5G access fees become a visible opex line. CelcomDigi’s 2025 performance materials indicate that 5G access fees, device subsidies, fibre expansion and network investment offset profit progression. That is the right economic frame: 5G monetisation must outpace the wholesale‑access and commercial‑acquisition costs attached to it.

The transition to a dual‑network model adds further complication. CelcomDigi publicly positioned itself as well‑placed to build Malaysia’s second 5G network, citing its national network experience and the billions of ringgit already invested in modernisation. The government chose U Mobile instead. This outcome is strategically uncomfortable for CelcomDigi. It remains a dominant retail operator and a DNB shareholder, but it did not get the clearest path to become the second‑network builder. U Mobile, for its part, gained a policy‑backed route to alter its competitive ceiling.

The involvement of Huawei Malaysia and ZTE Malaysia in U Mobile’s second‑network plans adds an extra geopolitical and supply‑chain layer. The question is not merely equipment brand. It is whether a challenger can turn policy selection and vendor partnerships into enough network differentiation to dent CelcomDigi’s scale advantage in 5G.

The growth engine is ARPA, not just subscribers

CelcomDigi’s customer base is vast, but the economics increasingly turn on account value rather than raw SIM count. The company reported more than 20 million users and service revenue above RM 10 billion in its recent performance disclosures. The more important detail is composition. Postpaid services, home fibre and enterprise services contribute more to growth, while prepaid remains more vulnerable to price competition and customer churn.

Postpaid is important because it creates a higher‑value relationship. A consumer on a postpaid plan can attach device financing, family lines, entertainment, roaming, home broadband, security services and enterprise perks. CelcomDigi’s use of ARPA language shows this shift. The company is trying to move from SIM‑level revenue to account‑level economics: more services per household, more services per business and more reasons for a customer to stay.

Home and fibre are part of this strategy, but they remain less material than mobile. CelcomDigi can use fixed wireless access, fibre resale or wholesale deals and bundled plans to deepen household value. The challenge is that Telekom Malaysia retains a structurally powerful position in fixed broadband and national backhaul. CelcomDigi can cross‑sell home broadband to its mobile customers, but that does not automatically make it the incumbent for national fixed access.

Enterprise services offer a higher‑potential version of the same move. CelcomDigi markets connectivity, business fibre, fixed wireless access, fast 4G mobility, API‑as‑a‑service, AI‑infused experiences, network APIs, digital financial security, smart‑city and health solutions. The business logic is to embed connectivity into a business process rather than turn it into a disposable data bundle. Once connectivity is embedded in operations, the customer relationship becomes stickier and the provider can sell around security, cloud, analytics and managed services.

The caveat is the scale of contribution. The company can tell a credible tech‑company story, but the financial base remains mobile. The enterprise and home‑broadband segments can improve the growth and valuation narrative; they have not replaced mobile as the cash‑flow engine. The most realistic 12‑to‑36‑month thesis is a disciplined migration towards higher‑value accounts, not a sudden reinvention as a software or cloud business.

Network registries show the merger in motion

The strongest infrastructure evidence is not the marketing phrase “largest mobile network operator”. It is how the old Celcom and Digi networks still appear in public resource registries while being integrated into a unified CelcomDigi framework. AS10081 / DIGI‑MY stays associated with DiGi Telecommunications Sdn. Bhd. AS10030 / CELCOMNET‑AP stays associated with the Celcom‑side heritage. AS4818 appears in the CelcomDigi context and is linked into wider downstream and AS‑SET structures.

This is how integration normally looks in telecoms. No serious operator deletes all autonomous system numbers, prefixes, peering policies and operational contacts in one go. That would create unnecessary disruption risk. Instead, the company maintains legacy resource stability while customer systems, brand, billing, core network and routing policy are progressively streamlined. The public‑registry trail thus becomes a map of integration sequencing.

Company commentary on network modernisation is consistent with this reading. CelcomDigi has described a nationwide network‑modernisation programme, a large number of 5G‑ready sites and broad 4G LTE/LTE‑A population coverage. The claim is not simply that the company has coverage. It is that the combined operator is trying to turn two legacy networks into one lower‑cost national platform.

For investors and specialist infrastructure readers, the resource registry matters because it avoids a false dichotomy. DiGi has not disappeared at the network layer. Nor is Digi a separate public‑facing company competing with CelcomDigi. It is part of an integration state where old resource identities coexist with a new group strategy.

Reliability, app friction and consumer background noise

CelcomDigi’s reliability record is mixed rather than broken. Public incidents include a 2023 fire‑related disruption affecting customers in parts of Pahang and Terengganu, and a 2026 system‑upgrade‑related disruption that caused brief mobile‑data outages for some users. These incidents fall into different categories. The first is physical‑infrastructure exposure. The second is closer to the IT and systems‑integration risk that often accompanies large telecom mergers.

The noise around digital services is more persistent. App Store, Google Play and forum commentary on the CelcomDigi app complains of slow loading, hard‑to‑find customer support, confusing menus and frustration after migration from the old Celcom Life and MyDigi experiences. This commentary does not prove network weakness. It shows customer friction at the moment CelcomDigi is trying to drive account value. A company that wants customers to buy more services through a single app cannot treat app quality as cosmetic.

CelcomDigi’s investments in customer service and apps confirm that management recognises the issue. The group has talked about AI, automation and multi‑touchpoint support, while continuing to update the unified app. The business question is whether these upgrades reduce friction before competitors use customer‑service dissatisfaction as a switching argument.

Discussions around fixed broadband create another signal. Malaysian forum talk sometimes portrays CelcomDigi fibre as dependent on TM/Unifi‑type access or wholesale layers, with a worry that incident resolution might involve responsibility‑handover between providers. The exact claim varies and is not an established fact for all products. The most useful takeaway is that CelcomDigi still needs to earn credibility in fixed access. It is recognised as a mobile operator; it is not automatically seen as the owner of the underlying fixed infrastructure.

Competition is becoming asymmetric

CelcomDigi’s biggest advantage remains scale. Its user base is materially larger than Maxis’s and U Mobile’s, and its post‑merger reach is wider than any single legacy operator’s. Scale gives it cash flows, retail visibility, network‑investment capacity and procurement leverage. It also gives regulators a reason to watch every move closely.

Maxis is the strongest premium‑quality comparator. Its user base is smaller, but its postpaid, home and enterprise profile is strong. Maxis can pressure CelcomDigi on high‑value customers, family bundles and service perception, rather than on raw scale. If CelcomDigi wants to lift its ARPA, Maxis is the rival most likely to make that move expensive.

U Mobile is the most disruptive policy variable. Its second‑5G‑network mandate, marketing built around speed and availability, and vendor choices give it a new role. A price‑aggressive challenger with a policy‑backed infrastructure path is more dangerous than a mere price‑aggressive challenger. CelcomDigi can still defend its coverage and core scale, but U Mobile can attack the 5G‑experience narrative.

Telekom Malaysia competes through fixed broadband, national backhaul, enterprise connectivity and wholesale infrastructure. It is not merely another mobile competitor. It shapes the economics of convergence. CelcomDigi can sell home and enterprise bundles, but TM’s position in fixed and backhaul remains a structural advantage in many parts of the market.

MVNOs add bottom‑end pressure and wholesale‑layer complexity. The merger remedies required ongoing attention to MVNO wholesale arrangements. CelcomDigi also has equity exposure to parts of the MVNO ecosystem, notably Tune Talk. This creates a market where wholesale, retail and investment interests can overlap. CelcomDigi can benefit from ecosystem breadth, but it also suffers low‑price erosion in segments where customers are highly price‑sensitive.

Rumours, weak signals and ownership speculation

Market noise around CelcomDigi falls into three buckets. The first is ownership speculation. Telenor’s long‑term position in Asian telecom assets is often debated, and market commentary periodically asks whether stakes might be adjusted after integration milestones. There is no basis for turning that into a sale claim. The useful point is that a dual Axiata‑Telenor ownership structure will keep capital‑allocation questions alive.

The second bucket is DNB economics. Reuters and investor commentary have highlighted 5G‑related accounting or cost effects in Malaysia for Telenor. This signal reinforces a broader concern: DNB exposure is not a minor operational detail. It can affect accounting, cash flows, shareholder perception and future network strategy.

The third bucket is post‑integration customer friction. App complaints, rumours about underlying fibre infrastructure, support frustration and outage talk all sit below the level of hard financial evidence. They are still worth watching, because telecom churn often starts with service irritation before it shows up in quarterly numbers.

Watchpoints

Watch the economics of DNB access and the second 5G network. CelcomDigi’s 5G margin will depend on wholesale costs, retail ARPA, U Mobile’s build pace and any future interconnection or roaming arrangements.

Watch spectrum renewal and re‑assignment, especially the 2600 MHz and 1800 MHz expiry timelines. Spectrum policy can alter CelcomDigi’s capacity advantage even if the company remains the largest operator.

Watch postpaid ARPA and convergence. The bull case strengthens if postpaid, home and enterprise growth offset prepaid erosion without excessive device subsidies.

Watch app, billing and customer‑support quality. Customer friction is strategically important because CelcomDigi’s account‑value thesis rests on customers trusting a unified service layer.

Watch TM and U Mobile separately. TM constrains fixed and enterprise convergence; U Mobile pressures the future‑5G narrative.

Watch any shift in Axiata or Telenor’s stance on the holding. Ownership changes would not erase CelcomDigi’s operating scale, but could alter capital allocation and strategic appetite.

CelcomDigi is therefore a strong but constrained operator. The legacy DiGi registration leads to a much larger merged platform, with scale, coverage, cash flows and synergy potential. The constraint is that Malaysia’s regulatory and 5G architecture prevents that scale from turning into unrestricted dominance. The company can still win, but it must do so through integration discipline, ARPA expansion, customer experience and enterprise/fixed stickiness, not simply by being the country’s largest mobile network.
