Indonesia is one of Southeast Asia's most popular destinations — and one of the best-value eSIM markets. Cheap data, solid urban coverage, and improving connectivity on tourist islands make it a great eSIM destination.
Networks in Indonesia
Telkomsel is the dominant network with the widest coverage across islands. XL Axiata and Indosat Ooredoo are strong in urban areas and popular tourist destinations. For Bali, all major networks perform well. For remote islands or East Indonesia, Telkomsel is the most reliable.
Pricing
Indonesia offers some of the cheapest data in the world — $0.50–$1 per GB. A 10GB plan valid for 7–14 days typically costs $5–$8.
Coverage by Destination
- Bali (Seminyak, Kuta, Ubud): Excellent — fast 4G everywhere
- Jakarta: Strong 4G/5G across the city
- Lombok: Good in tourist areas, weaker in rural south
- Komodo / Flores: Patchy — download offline maps before visiting
- Raja Ampat: Limited coverage; some areas have no signal
Tips
- Activate your eSIM before flying — Indonesian airport Wi-Fi is slow
- Download Grab (ride-hailing) and Maps offline before island hopping
- Hotel and café Wi-Fi is widely available as backup
