How to Activate Your SIM Card in Indonesia
Requirements:
- Unlocked phone
- Passport (for physical SIM)
- eSIM-compatible device (for eSIM)
Purchase the SIM
Buy from airport, store, or online (eSIM). Keep your passport handy for registration.
Insert or Install
For physical SIM, insert into your phone. For eSIM, go to Settings > Cellular > Add eSIM and scan QR code.
Complete Registration
Physical SIMs require IMEI registration (often done by seller). eSIMs are pre-activated.
Configure APN
Most SIMs auto-configure. If not, manually set APN to the operator's settings (e.g., telkomsel for Telkomsel).
Practical Tips
💡 Check Phone Compatibility
Ensure your phone is unlocked and supports the frequency bands used in Indonesia (4G: 900/1800/2100 MHz, 5G: n3, n40). Most modern phones work fine.
💡 Register Your IMEI
Indonesia requires IMEI registration for foreign devices to use local SIMs for more than 90 days. Short-term tourists are exempt, but registration is still needed for activation. Airport counters handle this.
💡 Keep Your Home SIM
If using an eSIM, you can keep your physical SIM active for calls/texts. For physical SIM, consider a dual-SIM phone or use an eSIM as backup.
