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.

Telkomsel prepaid

Local prepaid

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
