So I was traveling when my new iPhone 8 Plus was delivered on September 26th. I finally made it home last night, and my iPhone 8 Plus was waiting. I have yet to even open the outer box yet, but will be doing so soon. My iPhone 7 Plus is backing up right now, and as soon as it is done, it will be time to open the 8 Plus. One question. I ordered the 8 Plus under my wife’s number, but she is inheriting my 7 Plus and I get the new 8 Plus. Do I just put the sim card from my old 7 Plus into the 8 Plus and restore from my MBP, and then put the SIM card from the new 8 Plus into my 7 Plus and restore my wife’s phone from her backup on the Mac mini??
