After signing up for new service and porting a number from AT&T, one of our iPhones is unable to receive calls. When calling the number, an automated message from Verizon states "The number you dialed has been changed, disconnected or is no longer in service". The phone does ring once and shows the caller ID, but then immediately disconnects without allowing any actual conversation. This phone does allow outbound calls and both inbound and outbound messages, even with WiFi turned off.
We have worked with Verizon support for over 4 hours yesterday with no resolution. For reference, one of the other iPhones / numbers we ported at the same time is working fine.
We are regretting our decision to port our 3 phones, 3 watches and iPad from AT&T to Verizon. I didn't think support could be worse than AT&T, but at this point they are.
