eSIM or a SIM card for Indonesia: which fits your trip
Both get you online in Indonesia. They differ in where you buy them, what you show, and when they start working.
- Data only
- Installs at home
- Passport needed for a SIM

The short answer
An eSIM from this site installs at home and gets you online after landing, with no shop visit. A SIM card bought in Indonesia is registered at the point of sale, with your original passport, and it gives you an Indonesian number; the eSIM plans here are data only and run on Telkomsel in Indonesia.

When a SIM card makes sense
A SIM card bought in Indonesia runs on one of Indonesia’s three networks: Telkomsel, XL Axiata or Indosat. It gives you an Indonesian number, and packages are sold on the spot. The line is registered when you buy it, and the shop asks for your original passport. Indonesia also pairs SIM registration with device (IMEI) registration for phones bought abroad.
When the eSIM makes sense
You buy the eSIM online, ahead of the flight. Right after the payment, the code appears on screen, with a prompt to save that page’s link: it is where the code lives. Install it at home, within 30 days of buying, and switch it on after landing; choose it for mobile data. Your usual SIM stays in the phone for calls and bank codes. When the line will not connect, data roaming on that line is the store’s named fix for a line that does not start. The plans here are data only and run on Telkomsel in Indonesia; each names its data, days and price on the store before you pay.

Buy on VietSIMQuestions
Do I need an Indonesian phone number?
Only if you need to receive Indonesian calls or texts. The plans on this site are data only, so WhatsApp keeps your own number and your usual SIM stays in the phone for calls and bank codes.
Do I need my passport to get online in Indonesia?
For a SIM card, yes: it is registered at the point of sale, with your original passport, and Indonesia pairs that with device (IMEI) registration for phones bought abroad. For the eSIM, you buy it online before you fly and the store shows the QR code on screen right after payment; save the page link, because it is where your code is kept. If a plan carries a registration step, it is stated on the plan before you pay.
