How to read a number

+628111234567

+62Country code
Indonesia.
811Mobile prefix
The national part of an Indonesian mobile number starts with 8, and the first four digits (written 0811 and so on) are the operator prefix. Because Indonesia has no number portability, those four digits generally do identify the operator — 0811-0813, 0821-0823 and 0851-0853, for instance, are the prefixes Telkomsel publishes as its own. Written nationally as 0811…; that leading 0 is the trunk prefix and is dropped when dialling from abroad.
1234567Remaining digits
The subscriber number. Indonesian mobile numbers are not a fixed length — the national part is commonly 9 to 12 digits. Telkomsel notes that the two digits after the prefix map to the HLR home region.

Written nationally as 0811 123 4567.

Carriers & prefixes

Mobile prefixes by carrier.

No number portability — prefixes still map to the current carrier.

Porting rules in full

Indonesia has no mobile number portability — changing operator means changing your number. That makes the prefix a reliable guide to the current operator, the opposite of India, Russia, Turkey and the UAE. This may change: in September 2026 the Constitutional Court took up case 319/PUU-XXIV/2026 (first hearing 3 September 2026), in which the petitioner asks that Article 14 of the Telecommunications Law (Law 36/1999, as amended by Law 6/2023) — the freedom to choose a telecoms network — be read as including the right to keep your number when switching operator. The petitioner left the technical mechanism to the government. The Ministry of Communication and Digital (Komdigi) has said it will follow the court’s ruling and issue new rules if needed. So treat this line as provisional and check the latest announcements.

Network-experience stars are derived from the awards each operator won in the Opensignal report of 2026-07 (data collected Apr 01 - Jun 29, 2026): the most-awarded operator gets 5 stars, the rest proportionally, with a shared award counting as half. They reflect network testing only — not prices or customer service. Test report →

  • Telkomsel Mobile carrierVeteran
    founded 1995
    Network experience★★☆☆☆ Strongest in: coverage, 5G games, 5G voice apps

    0811~0813, 0821~0823, 0851~0853

    Owned by Telkom Indonesia / Singtel. These prefixes are the ones Telkomsel publishes itself; it also explains that the two digits after the prefix map to the HLR home region.

  • Indosat Ooredoo Hutchison Mobile carrier
    Network experience★★☆☆☆ Strongest in: consistent quality, availability, video, 5G games

    One of Indonesia’s three main operators (ioh.co.id). It does not publish a full prefix table, and this site will not assemble one on its behalf.

  • XLSMART Mobile carrierVeteran
    launched 1996 — its predecessor XL; merged with Smartfren into XLSMART in 2025
    Network experience★★★★★ Strongest in: reliability, download speed, upload speed, games (10 in total)

    Full name PT XLSMART Telecom Sejahtera Tbk. Its own site lists five brands under it — XL, XL Prioritas, XL SATU, Smartfren and Axis — so the XL, Axis and Smartfren that older guides describe separately are now one company. It likewise publishes no full prefix table.

SIM cards & keeping a number

Since 19 January 2026, Permen Komdigi 7/2026 applies: SIMs (eSIMs included) are sold inactive and only switched on after registration. Foreigners register at an outlet with a passport or KITAS/KITAP residence permit, checked by staff; the regulation doesn’t require foreigners to do a face scan (Indonesians must). Each person may register at most 3 prepaid numbers per operator.

Foreign phones used with an Indonesian SIM need IMEI registration (customs rule): at an operator outlet for stays up to 90 days, or with customs for longer stays (max 2 devices per person).

Keeping a number: Telkomsel officially lets top-up validity accumulate up to 365 days, but a SIM that hasn’t connected to Telkomsel’s network for 90 consecutive days enters the grace period. Whether roaming abroad counts isn’t stated, so keeping a number long-term from abroad is unreliable.

Network
Telkomsel’s own network (MNO)
Price
SIM and top-up amounts vary; an accumulating validity-extension package (Paket Perpanjangan Masa Aktif) is also available — price not checked
Keeping the number
Telkomsel FAQ (from 9 Nov 2024): validity from top-ups accumulates up to 365 days; package validity doesn’t accumulate (the longest applies), except the validity-extension package. A SIM not connected to Telkomsel’s network for 90 consecutive days enters the grace period (masa tenggang): no outgoing calls or SMS until you top up or buy a package. After the grace period the number is blocked; unblock via *888*89# or at a GraPARI store. A 2023 Telkomsel article gives a 30-day grace period, then 85 days to reactivate before the number is recycled (the new FAQ gives no day counts)
ID check
Permen Komdigi 7/2026: passport or KITAS/KITAP registered at an outlet, max 3 prepaid numbers per operator; foreign phones also need IMEI registration (outlet within 90 days, customs beyond)
SMS & calls
A normal Indonesian number. Telkomsel’s official X account (2019): you can still receive SMS abroad, free for the recipient; China is on Telkomsel’s roaming destination list

Pros

  • Best coverage in Indonesia
  • Receiving SMS abroad is free (official support reply)
  • No face scan for foreigners

Watch out

  • 90 days without connecting to Telkomsel’s network triggers the grace period — unreliable to keep from abroad
  • Foreign phones staying over 90 days need customs IMEI registration
  • Grace and recycling day counts only appear in a 2023 official article, not the new FAQ
