Quick answer
- Toggle airplane mode for ten seconds — the single most effective fix.
- Confirm data roaming is on for the eSIM line.
- If it still fails, select the network manually instead of automatically.
Work through in order
- Toggle airplane mode
- Check the eSIM line is enabled
- Enable data roaming on the eSIM line
- Set the eSIM as the data line
- Restart the phone
- Select a network manually from those listed on your plan page
How to select a network manually
On iPhone: Cellular → the eSIM line → Network Selection, turn Automatic off and pick from the list. On Android the same option sits under that line's mobile network menu. The scan can take up to a minute.
If you have just landed, give it five minutes — some networks take a while to register a new device.
