I had just gotten my iPhone 5 stolen, and I'm trying to switch back to my iPhone 4 so I can at least have a phone until i get a new one. But when I go to switch it, it tells me it's going to send a text message to my number, but I don't have my iPhone 5 in possession right now to get the verification code, so what do I do to activate my iPhone 4?
Did you report your device as stolen to VZW? If not, I would call them at 8009220204 so they can block the device as stolen and also restrict the sim card. If you had Find my iPhone turned on you can track your phone at icloud.com. Alternatively, you can always go into a corporate VZW store and have them help you activate your old device.
