Your eSIM works on Telkomsel, XL, Indosat and 3. The phone joins the strongest partner network where it is, and the eSIM cannot be locked to one carrier. This is automatic, so you do not pick a network by hand. Indonesia has 123 mobile subscriptions per 100 people, so the main networks reach most populated areas.
A data-only travel eSIM on a country plan gives you mobile data in Indonesia. It has no local phone number. WhatsApp and app calls work over data, and your own SIM stays in for calls and bank texts.
Data can be added to the same eSIM online without a new QR code, so a longer trip does not need a second install. Prices are in US dollars, shown before payment, with nothing added at checkout.
5G is the newest generation on these networks, and coverage depends on where you are. About 73 per cent of people in Indonesia use the internet, and the networks carry 123 mobile subscriptions per 100 people. Expect strong data in cities and main tourist areas, and weaker service in remote islands and rural regions.
Telkomsel, XL, Indosat and 3 are the networks your eSIM can use. Because the phone joins the strongest partner network where it is, it moves between them as you travel rather than staying on one carrier. That suits island hopping, where signal varies from place to place.
The eSIM is data only. There is no local phone number, so calls to local businesses are not part of the plan. WhatsApp and app calls work over the data connection, and your own SIM stays in for calls and bank texts. If you need to receive a bank code, keep your usual line active for it.
Coverage figures are checked as of 2026-10-31. The internet user share comes from ITU via the World Bank.
The phone must support eSIM and be carrier free. Most recent iPhone, Samsung Galaxy and Google Pixel models do. Check both points before you buy, because a phone tied to one home operator may not accept a travel eSIM.
Once installed, the eSIM uses the local networks automatically. Your own SIM stays in the phone for calls and bank texts, so you keep your usual number while data runs on the eSIM line.
The APN is set automatically on most phones. If data does not start after you land, turn on data roaming for the eSIM line. That single setting fixes most first connection problems, and no manual APN entry is usually needed.
Install the eSIM on Wi-Fi before your flight so it is ready when you land. The QR code arrives by email in minutes after payment. Your plan days start when the eSIM first connects in Indonesia, not when you buy it, so early setup costs you nothing.
Payment is by Apple Pay, Google Pay or a card the bank confirms. Prices are in US dollars, shown before payment, with nothing added at checkout. Plans come in sizes of 1, 2, 3 and 5 GB and lengths of 7, 15 and 30 days.
If you run low, data can be added to the same eSIM online without a new QR code. Keep the eSIM line set for mobile data and leave your own SIM in for calls and bank texts. On arrival, the phone joins the strongest partner network where it is.
