Roaming vs eSIM in Indonesia: cost comparison

Roaming your home carrier in Indonesia costs significantly more than a local eSIM.

Indonesia has over 17,000 islands โ€” roaming coverage is inconsistent. US and EU carriers charge $10โ€“20/day with limited guarantees of coverage on outer islands.

Telkomsel's AS and simPATI tourist SIMs available at Bali airport offer 30โ€“50 GB for $9โ€“18. This is exceptional value. The trade-off is a moderate airport queue and some registration steps. An LTE.app Indonesia eSIM on Telkomsel is similarly priced with zero queuing.

LTE coverage in Indonesia for Galaxy S23 users

Indonesia uses LTE bands 1, 3, 8, and 28. Telkomsel has the widest national coverage across Java, Bali, and most major islands.

Bali is well covered in tourist areas (Kuta, Seminyak, Ubud, Nusa Dua). Remote Bali highlands and some beaches may have gaps. Lombok and the Gili Islands have coverage in main areas but gaps on undeveloped beaches. Outer Indonesian islands have limited connectivity.
