How to Check and Set APN Settings

What Are APN Settings?

APN settings tell your phone how to connect to mobile data networks. If they're incorrect or missing, your eSIM won't be able to access the internet.

Important: If you've already connected to the internet using your WonderConnect eSIM before, APN settings are unlikely to be causing your current issues - the fact that you connected previously means they're already configured correctly. Check other possible solutions in our troubleshooting guide.
