I was supposed to use the new SIM card numbers but i used the numbers from my old SIM card and it won't let me inactivate the phone to try it over. Any ideas on how to fix it because my phone has no service until i can get it fixed.thanks
Added (1). When you are changing from the iPhone 4 to the iPhone 5, you have to register your phone on the service companies website. I needed to take the numbers from the sim card in my iPhone 5 and use those to register it but i accidentally used the sim card numbers from my iPhone 4. The iPhone 5's sim card is smaller so you can't replace them
