Upgrade iPhone - SIM QuestionI am upgrading from iphone 5 to iphone 5S (purchased from apple.com). Do I have to swap out my SIM card when I get it in the mail?
I ordered the iPhone 5S from apple.com, and currently use an iPhone 5. I understand how to back up my iphone 5 and restore on the 5S to copy all of my data. But my confusion is with the SIM card in my existing phone...
When it arrives in the mail, do I have to put my existing SIM card into the 5S? My carrier is AT&T. If anyone could help I would appreciate it! Thank you 🙂
iPhone 5s, iOS 7, replacing iPhone 5 with iPhone 5S
