Who I have the same questioned this topic

Purchased a new iPhone 13 Pro.  It was activated at the store, but got home and it didn't work.  After hours on the phone with VZ, we finally took the sim card out of the old phone and got the new phone to work.  We were advised to get a new sim card.  Went back to the store, and after hours of working with the phone, we got it to work only to have it fail again.   More work, and VZ got it to work.  We left the store, and it stopped again.  We couldn't use the phone or texts.  We were told that this was a recent issue with the phone, and that they had five phones returned that day.  Does anyone know what the issue really is (it can't be recent based on searches on the internet), and when it will be fixed?
