Internet and Wi-Fi in Indonesia
What to expect from mobile coverage, public Wi-Fi and data options in Indonesia — and the simplest way to get online as a visitor.
Mobile coverage in Indonesia
Good 4G in Bali, Java and cities; patchy on remote islands and in the mountains.
Local networks
Our Indonesia eSIM connects to these local mobile networks, the same ones domestic SIM cards use:
- Smartfren
- Telkomsel
- XL
- Indosat
- PT Natrindo Telepon Seluler
- Fren/Hepi
Can you rely on public Wi-Fi?
Hotels, cafes and airports in Indonesia usually offer Wi-Fi, but it rarely helps when you need a connection most: navigating between places, checking transport in real time, or calling a ride from the street. Public networks are also unencrypted more often than not. Treat Wi-Fi as a bonus, not a plan.
The easiest way to get online
A prepaid eSIM for Indonesia installs on your phone before you leave home and connects to a local network automatically when you land — no store visits, no paperwork, no roaming fees. Plans start at $0.51.
