7 Best eSIM for Indonesia 2026 (Bali to Komodo)

Your Grab driver in Bali cannot find you because Google Maps will not load. The airport SIM counter has a 40 minute queue. And your carrier just charged $18 for 50MB of roaming data you used checking one email. This is what happens when you arrive in Indonesia without an eSIM for Indonesia already installed on your phone.

Indonesia stretches across 17,000 islands. Telkomsel controls roughly 48% of the mobile market and remains the only carrier with reliable signal on smaller islands like Flores and Komodo. Indosat Ooredoo Hutchison comes second, performing well in cities but weaker in mountainous areas. XL Axiata handles urban zones fine but drops off quickly outside main towns.

I tested eSIM plans across Bali, Lombok, and Java over three separate trips. The seven providers below earned their spot through real performance on Indonesian networks.

1. Amigo eSIM

Amigo eSIM routes its Indonesia plans through Telkomsel, which gives you the widest coverage possible across the archipelago.

That means solid LTE in Ubud's centre, along the Canggu stretch, and even on the boat to Nusa Penida where other providers drop out.

Plans start around $5 for 1GB over 7 days. If you plan to scooter through rural Bali or ferry to the Gili Islands, Telkomsel routing makes Amigo the safest bet for signal outside tourist hubs.

What you get:

Why Amigo for eSIM for Indonesia: Telkomsel routing is not something every provider offers. In a country where carrier choice determines whether you have signal on a Gili Islands beach or a Flores hiking trail, Amigo's network partnership puts it ahead for travellers leaving the main tourist strip.

2. GigSky

GigSky automatically switches between available Indonesian networks rather than locking onto one. That dynamic routing adapts as you move between islands or from a city to a rice terrace.

Every new signup gets a free 100MB trial plan lasting 7 days with no credit card needed. Paid plans start at $3.99. The unlimited option throttles to slower speeds after 2.5GB per day but never cuts you off entirely.

What you get:

Why Gigsky for eSIM for Indonesia: The free trial alone makes it worth installing before you land. Test the signal at your Bali villa or Jakarta hotel. If it performs, upgrade to a paid plan in seconds.

That makes it the obvious pick for backpackers island hopping from Singapore through Batam into Bali. Coverage reaches 150+ countries, so a single profile follows you across borders.

The Indonesia-only plan starts at $3.40. Data speeds run on 4G LTE with strong urban performance in Jakarta, Denpasar, and Surabaya.

Plans activate automatically when you land. The built-in ad blocker and virtual location tool set Saily apart from data-only competitors. Coverage spans Jakarta, Bali, and most Indonesian islands on 4G and 5G where available.

What you get:

Why Saily for eSIM for Indonesia: Digital nomads in Canggu and Ubud often work from café Wi-Fi that is wide open to snooping. Saily's NordVPN pedigree means your data stays private on every network you touch across the islands.

5. Airalo

Airalo covers Indonesia through its Indotel plan, which runs on the Indosat and Three (Hutchison) 5G networks.

The local Indonesia plan starts at $4.50 for 1GB over 7 days. A 20GB package for 30 days costs $40. The regional Asialink plan covers multiple Asian countries on one profile, useful if your trip includes a side hop to Singapore or Kuala Lumpur.
