Problem using a former Verizon phone for a temporary replacement
I have recently sent my wife's Samsung S21 Ultra for repair. I placed her SIM card in an LGV10 from when I was a Verizon customer. The phone initially displayed a message that the SIM card was not a Verizon card. The phone is not locked (she visited a Verizon store this AM) and it will allow her to send and receive text messages and she can receive phone calls. It will not allow her to send/receive group messages nor can she make phone calls. It will also not perform any functions associated with the data connection (browse the internet, Google Play store, etc.). The associates at the AT&T store were unable to provide any help and said to call customer service. I called them and they said visit the Verizon store (which we've already done). Any suggestions on solving the problem with making phone calls and using the data connection?
