If your eSIM shows signal but apps are not working, it usually means your phone is connected to a network but mobile data is not being properly used.
This is one of the most common issues travelers face and is usually easy to fix.
Quick answer: Check that your eSIM is selected for mobile data, data roaming is enabled (if required), and restart your connection.
