If your travel eSIM installed correctly but does not work abroad, roaming settings are one of the first things to check.
Many travelers assume roaming should stay OFF because roaming charges are normally something to avoid. But travel eSIM plans often work differently.
Most international eSIM plans use roaming agreements with local partner networks. That means Data Roaming usually needs to be ON for the eSIM line.
This guide explains exactly how to fix eSIM roaming not working, what settings to change, and how to restore mobile data fast.
Quick answer: Turn Data Roaming ON for the eSIM, select the eSIM as your mobile data line, check APN settings, restart your phone, and try manual network selection.
Why travel eSIM roaming works differently
Traditional roaming can be expensive on your home carrier.
Travel eSIM providers usually buy access to partner networks in each country. Your phone connects through those agreements.
So for many travel plans:
- Roaming ON = required
- Roaming charges = already included in your plan model

1. Turn Data Roaming ON
This solves many issues immediately.
iPhone:
- Settings
- Cellular
- Select your eSIM
- Turn Data Roaming ON
Android:
- Settings
- Network & Internet
- SIMs
- Select eSIM
- Turn Roaming ON
2. Make sure eSIM is selected for mobile data
If your primary SIM is still selected for data, the eSIM may not be used.
Fix:
- Open SIM settings
- Select Mobile Data
- Choose the travel eSIM
3. Restart your phone
Simple but effective.
Restarting forces fresh network registration and often fixes roaming connection problems.
4. Use airplane mode reset
- Turn Airplane Mode ON for 15 seconds
- Turn Airplane Mode OFF
- Wait for reconnection
5. Check APN settings
If roaming is ON but data still fails, the APN may be wrong.
Fix:
- Open APN settings
- Use exact provider values
Example many travel plans use:
- APN: data.esim
Only use provider-approved values.
6. Try manual network selection
Your phone may auto-connect to a weak or unsupported carrier.
Fix:
- Open Network Selection
- Disable Automatic
- Try another available network
7. Confirm destination coverage
Some regional plans do not cover every country equally.
Check:
- Is the country included?
- Did you cross borders recently?
- Is the plan expired?
