I have an iPad 2 with AT&T cellular service, updated to iOS 7.. I have never activated the AT&T cell service, and it says "No Service" where it used to say AT&T in the top left corner in iOS 6. I'm wondering if it says No Service because if in iOS 7 they changed what is displayed if the service is not activated, or if there something wrong. I can set up an AT&T account in System Settings but since I don't want to activate the cellular service I don't want to do that. Thank you in advance for your help.
