There are multiple reasons why your eSIM may appear connected to the network, but is not getting an Internet connection on a 4G/LTE/5G network.
You may experience the following problems when the eSIM is not connected to a data network:
Extremely slow download/upload speeds
Only "E" (Edge) appears in the status bar, no 4G/LTE
Unable to use the internet, even though eSIM is getting a connection
