After installing the Android 11 update last night, my Galaxy S10+ no longer can get connected to T-Mobile’s network!!!
I have tried restarting the phone, taking the SIM cart out and re-inserting it, neither way works.

Call and text are still working but just no internet.

I’m pretty sure my SIM card is fine because it’s working on my other phone.

Please help!!!

Verify mobile data is enabled in the Settings.  Verify the APN Settings, which can be found at the following link.

Try doing a Network Reset, which can also be found in the Settings, usually under System.
