One of the phones my account has the same issue. she cannot make calls or receive calls. took it to a store and we were told that Verizon sent an update to the phone and that a lot of phones cannot accept the update. so now the phones do not work . basically her phone is a piece of junk.
not even 2 years old and we have not paid it off yet. Verizon does not want to answer me about what is being done about this.
