Frequently Asked Questions

Do I need IMEI registration for eSIM in Indonesia?

No! Tourist eSIMs bypass the IMEI registration requirement that applies to local SIM cards. This saves you the hassle of registration at shops and makes activation instant.

Will my eSIM work on all 17,000 islands?

Coverage is available on major islands and tourist destinations, but not all 17,000 islands have cellular coverage. Popular spots like Bali, Java, Lombok, and the Gilis have excellent coverage. Remote islands may have limited or no signal.

Can I use my Indonesia eSIM in Malaysia or Singapore?

No, Indonesia-only eSIMs work exclusively within Indonesia. For travel to Malaysia, Singapore, or other ASEAN countries, you'll need to purchase a Southeast Asia regional package.

Is 5G available in Indonesia?

Yes, 5G is available in Jakarta and expanding to other major cities. However, 4G LTE coverage is excellent on main islands and more than sufficient for all travel needs including video streaming.
