eSIM for Indonesia and Bali: connected in paradise

An eSIM for Indonesia keeps you connected from the rice fields of Bali to the temples and the islands around them. Indonesia is outside the European Union, so roaming is expensive there. With an eSIM you have internet right away at a fixed price, ideal for anyone travelling or working as a nomad. This guide explains everything with tables, tips and a FAQ.

Do I need an eSIM in Indonesia?

Yes, usually. Indonesia is not an EU country, so your home data is charged at the expensive outside-Europe rate. An eSIM gives you a fixed amount of data at a price known in advance, while your home number stays active. It is also more convenient than buying a local SIM card on the spot, which sometimes requires registration.

Outside the EU: on arrival, turn off the mobile data of your home SIM card and use only the eSIM, to avoid expensive roaming.

Keeping your home number

Thanks to dual SIM, your home number stays reachable for calls and bank codes, while the eSIM handles your data. Set the eSIM as your default data line and turn off the mobile data of your home SIM. More on this in dual SIM with eSIM.
