I have a dumb question, when I get my new phone do I need to take the Sim card out of my old one and put it in the new one?
You know what, I haven't upgraded my phone with a GSM line before within the same carrier (AT&T in this case), so I'm curious as well.
I reckon I just need to remove the nano SIM card from my iPhone 5 and put it inside my iPhone 6 Plus and then restore from backup the iPhone 6 Plus using iTunes. Is that correct? Or do I restore from backup first before putting in the SIM card? Or does it even matter what order?
