Switch your Indonesia eSIM on when you land
- Line on
- Mobile data on the eSIM
- Roaming only if needed

The short answer
After landing, turn the eSIM line on and choose it for mobile data. If data does not start, turn on data roaming for the eSIM line and try again. Keep data roaming off on your home line, so it cannot run up charges.

On the eSIM line
Switch that line on, then set it as the one for mobile data (Cellular Data on an iPhone). If data does not start, turn on data roaming for the eSIM line and try again. Make sure the phone cannot move mobile data between lines: switch that setting off, and your home line never becomes the fallback.
On your home line
Switch data roaming off on the SIM you normally use. The usual line can stay on for calls and texts to your number; your home carrier bills those.
Give it a minute
The phone may take a few minutes to find the network. The signal bars and the network’s name appear next to the eSIM line: one of Indonesia’s networks, Telkomsel, XL Axiata or Indosat.
If it fails (Switch it on after landing)
Take the not connecting steps one by one. Install within 30 days of buying; if your trip starts later than that, write to the store’s support before installing.
