The short verdict
For Indonesia, Telkomsel is the carrier that matters — the largest Indonesian carrier by far, with the widest coverage across Java, Bali, Sumatra, Sulawesi, and Kalimantan. Flysimio routes through Telkomsel at the best price we found at a competitive price per gigabyte on the same network. XL Axiata and Indosat are competitive in major cities but fall behind Telkomsel on the outer islands and rural areas. For Bali and central Jakarta any provider works; for anywhere else in the archipelago, Telkomsel is essential.

How this table is priced. Flysimio prices are read live from our carrier catalog every time this page loads, so the figure here is the figure at checkout. Competitor prices are the US-dollar price shown on each provider's own site, read on the date in the last column and linked to the page we read it from; promotional prices are marked alongside the list price. Price per GB is the plan price divided by its included data — unlimited passes have no per-GB figure and are ranked by total price instead.

Frequently asked questions
What is the best eSIM for Indonesia?
Flysimio on Telkomsel is a strong Indonesia pick for most travelers, and was cheaper than Nomad at 5 GB when we checked in August 2026 — though the two run close per gigabyte on larger plans, so check the dated index above. Telkomsel has the widest coverage across Indonesia's 17,000+ islands, and for travel beyond Bali and Java it is the only reliable choice.
Does eSIM work in Bali?
Yes. Bali has excellent 4G LTE coverage on all major Indonesian carriers. Seminyak, Kuta, Ubud, Canggu, and Sanur are all well covered. Remote rice terraces and the Kintamani volcano area have 4G on Telkomsel.
Does eSIM work in Komodo?
Yes, on Telkomsel. Labuan Bajo (the gateway town) and Komodo Island have Telkomsel 4G. Pink Beach and more remote areas of the park have reduced signal. Download offline maps and content before island-hopping.
Which eSIM uses Telkomsel in Indonesia?
Flysimio and Nomad route through Telkomsel for Indonesia. Airalo and Saily typically use XL Axiata. Always confirm the carrier before purchasing for any travel outside Bali and Java.
Does eSIM work in Raja Ampat?
Partially. Telkomsel reaches the main islands of Raja Ampat (Sorong, Waigeo, Misool) but signal is limited in remote dive sites and uninhabited islands. Download offline maps and be prepared for limited connectivity in this remote destination.
How much data do I need for two weeks in Bali?
For moderate use (maps, social, browsing), 5 GB is sufficient for two weeks in Bali. Add more if you plan to hotspot your laptop or stream video. Bali has fast 4G so data loads quickly.
