I messed up Activating my Iphone 6 While activating my iphone, I accidentally skipped the section where you call and activate your phone. My phone isn't sending messages or calls, and cellular isn't working. Is there any other way I can make it work?
What section where you call and activate your phone? there was no phone call involved in setting up the iPhone 6 (or my previous iPhones either).

If you are not getting any cellular services you will need to contact your carrier. The simplest way to do this is to call 611 from the phone, but they may need you to reset the phone (losing the call) so it may be simpler to just go to your carrier's closest brick-and-mortar store.
