When I went to change my plan to the shared everything plan the other day, I was told by customer care that my iPhone 5 is showing up as a "non-VZW device". I recently got a replacement through insurance, does this have anything to do with it?
Was the iPhone 5 active and on your VZW line after you got it replaced? Or did you get it replaced, kept it inactive and decided to activate it when changing your plan to a shared everything?
Once your SIM is in, you have to call *228 to program your device. Otherwise, your device won't be activated on the line associated with the SIM. Or you can head over to My VZW and manually do it.
I've had that problem when I got my iPhone 5. It's a problem with their end. I had to have them switch my plan. Not sure what they did but all of it works from my end. I want to say they had to reset my account.
