eSIM not working abroad? How to fix it
Your eSIM is installed, but no internet is coming through? In most cases the problem is a setting, not the eSIM itself. This guide walks you through the checklist so you can solve it quickly on your own.
Did the problem start right after you switched phones? Then the cause is usually the move itself; see transferring your eSIM to a new phone.
First: the two most common causes
Most problems come down to one of these two settings:
1. Data roaming is not switched on for the eSIM line. A travel eSIM technically works through roaming on the local networks, so this setting needs to be on. 2. Your home SIM card is still set as the default data line. Set the eSIM as your default data line.
Check these two first. They solve the vast majority of cases.
The full checklist
| Check | What to do |
|---|---|
| Data roaming | Switch it on for the eSIM line |
| Default data line | Set it to the eSIM |
| Mobile data | Make sure it is on |
| Have you arrived? | The eSIM only works at your destination, not at home |
| Network selection | Set it to automatic, or manually pick a local network |
| Restart | Turn your device off and back on |
Still not working?
Sometimes it takes a moment for your device to connect to a local network, so give it a few minutes. If that does not help, try manually selecting a different local network in your network settings. Also check that you activated the eSIM correctly using our guide on activating an eSIM.
Prevention is better
You can avoid most problems by installing at home over Wi-Fi in advance and getting the settings right. See also dual SIM with eSIM for the correct configuration of your two lines.
Frequently asked questions
My eSIM does not work at home, is it broken?
No. A travel eSIM only works at your destination, on the local network. At home that is completely normal.
What is the most common cause?
Data roaming is not switched on for the eSIM line. That is almost always the solution.

Conclusion
If your eSIM is not working, it almost always comes down to a setting. First check that data roaming is on for the eSIM and that it is set as the default data line. Otherwise, run through the checklist and restart your device. If it still does not work, the esimzu support team is ready to help you.
