If your ByeRoaming eSIM shows no bars or no data, start with line and roaming settings: enable the travel eSIM, set it as the cellular data line, turn on Data Roaming for that line only, then toggle Airplane Mode. Most “installed but offline” cases are fixed by those steps or by manual network selection.
Checklist
- Confirm the travel eSIM is on and selected for Cellular Data.
- Enable Data Roaming on the travel line (not necessarily on your home SIM).
- Toggle Airplane Mode on/off, or restart the phone.
- Verify you are in a covered country for that plan (destinations).
- Check the plan has not expired and still has data.
- Try manual network selection if the phone stays on “No service”.
- Reinstall only as a last resort — some profiles cannot be reused after deletion.
