The same thing was happening to me.. and when I called they said that it was because of a tower upgrade that was in my area which didn't make any sense because I had data connections sometimes but never had mobile voice service. And all the other devices in my home was working.
Understood. Can you please send me a private message with your phone number, PIN number and current address?
