I lived in Mexico for the last year and purchased a AT&T IPhone 4 to use there on Telcel. Now that I am back I upgraded to an IPhone on my Verizon account. I activated the new phone from my ICloud and had all my contacts and so forth pulled in from the backup. My wife also has an IPhone and while in Mexico I had to dial as an international call, so I modified her number back to normal without the international code and tried to call her. But guess what, it still. Tries to dial as an international number and I get Mexican messages saying the number doesn't exist. What do I have to do in order to make it be recognized as a USA number? Any help appreciated.
