Summary
- The 10 July ranking and 14 July no-objection notice reserved final validity for the communications minister. Meutya Hafid signed the final winner papers on 21 July; the bid table did not change.
- At 700MHz, XLSmart won 30MHz for Rp1.0602tn, Telkomsel 20MHz for Rp642.5bn and Indosat 20MHz for Rp507.48bn.
- At 2.6GHz, Telkomsel won 80MHz for Rp545.84bn, Indosat 60MHz for Rp372bn and XLSmart 50MHz for Rp231.6bn.
- The six offers total Rp3.35962tn. That calculated sum is neither total network capex nor revenue, annual cost or verified same-day cash; deployment and five-year obligations come next.
The signature matters because Indonesian officials had deliberately separated ranking from legal finality. Komdigi published the auction results on 10 July but said the listed operators became valid winners only after ministerial designation. The objection period then ended on 14 July without a challenge, leaving one binding act. Meutya Hafid's signature on 21 July performed that act.
Reporting it as another auction would obscure what changed. No new bids were submitted and the ordering was not revised. The operators moved from provisional winners with known offers to final winners entitled to proceed towards spectrum rights, fees and rollout commitments.
Low-band reach and mid-band capacity produced different winners
The 700MHz band is valuable because lower frequencies generally travel farther and penetrate buildings more effectively than higher ones. XLSmart secured the largest block: 30MHz at Rp35.34bn per MHz, for Rp1.0602tn. Telkomsel took 20MHz at Rp32.125bn per MHz, totalling Rp642.5bn. Indosat also took 20MHz, at Rp25.374bn per MHz, for Rp507.48bn.
That gives XLSmart the widest newly awarded low-band position in this selection. It does not establish coverage, speed or profit. Network design, existing holdings, radios, towers, backhaul, customer devices and capital deployment determine how much practical reach a licence creates.
At 2.6GHz, the strategic order differs. Telkomsel won 80MHz at Rp6.823bn per MHz, totalling Rp545.84bn. Indosat secured 60MHz at Rp6.2bn per MHz, or Rp372bn. XLSmart obtained 50MHz at Rp4.632bn per MHz, or Rp231.6bn.
The wider contiguous capacity can support high-throughput 5G where sites and demand justify it, but propagation is shorter than at 700MHz. Telkomsel therefore leads the new mid-band width, while XLSmart leads the low-band award. Indosat's middle position—20MHz low band and 60MHz mid band—still creates a combined reach-and-capacity option. Spectrum width is an input to the network, not proof of the service it will deliver.
Rp3.35962 trillion is a rights ledger, not a rollout budget
Adding the six published totals gives Rp3.35962tn. The arithmetic is useful because it establishes the disclosed economic size of the winning offers. Its boundary is just as important.
The number is not the three operators' total capital expenditure. Towers, antennas, radios, fibre, power, software, installation and customer acquisition will require separate spending. It is not annual cost or revenue. The material reviewed does not establish that all Rp3.35962tn changed hands on 21 July; payment terms and licence issuance remain evidence to watch.
Nor do per-MHz prices make the bands directly comparable. A 700MHz unit carries different propagation value and scarcity from a 2.6GHz unit. Operators also start with different networks and spectrum portfolios. Dividing one total by another cannot reveal expected return without rollout cost, utilisation, pricing and churn assumptions.
Five-year obligations turn optionality into execution
The final rights come with forward-looking commitments. Winners must pay applicable spectrum-right fees and, within five years, provide at least 4G service in selected locations drawn from a ministry-defined total of 538 villages or wards. The wording does not assign all 538 locations to every operator.
They must also reach at least 51% of Indonesia's national population with 5G in the cities and regencies to which each has committed. That is a future target, not a statement that current 5G coverage already equals 51%. Operator-specific lists and schedules will be necessary to judge the burden and additionality of each promise.
The investment chain now begins: formal licences and payment, spectrum planning, radio and antenna orders, site upgrades, backhaul and power, integration, testing, coverage verification and commercial monetisation. Low band can reduce the number of sites needed for geographic reach, but it cannot eliminate backhaul or service-quality constraints. Mid band can add capacity, but only where dense enough deployment and compatible devices bring traffic onto it.
The next evidence should therefore be disaggregated. Licence documents will define the legal rights. Payment schedules will show when the auction consideration is due. Operator plans will reveal locations, capex and sequencing. Independent coverage and quality measurements will test whether the obligations became usable service. Revenue and traffic data will show whether the spectrum created a return.
The 21 July signature closed the selection process; it did not close the investment case. Indonesia now has final winners and a stable bid ledger. The economically important uncertainty has moved from who owns which block to how three unequal combinations of reach and capacity will be financed, built and used over the next five years.
