I am trying to switch my iPhone 5s over from Straight Talk to Verizon Wireless Prepaid. I already had my number ported over but when I put the Verizon Wireless sim card inside of the iPhone and turn it on, after I go through the set-up tutorial, it will not allow me to access the home screen, but instead locks the phone and stays on an Activation Required screen. On this screen in prompts me to input my Apple ID information, which I do, but even after I do that it says that the activation was unsuccessful. I don't know what to do next.
