As far as the original poster goes, since it has only been a day I would say the number port might not have taken correctly for some odd reason; of course I am assuming you did port your number.

I hate to say this, but I have read somewhere that just getting a number change to a VZW prefix usually solves the problem. I know this might not be an option and have heard of this happening before with porting numbers.

Before you give up, and I know that cust service can be totally raggedy in calling back etc. ( Have been with VZW since they were airtouch so I know ). Call them back or call them if you have not and tell them about problem. If you have already I would suggest writing a complaint on planetfeedback.com. This will generate a call from someone, I know this.

But before you do please try tech support if not already
