Can I transfer data to new phone before moving SIM card over?
My wife has an iPhone 6. We just ordered her an iPhone 11. We all use iCloud for backups. I want to set up her new phone and once it is working, unlock the iPhone 6 so we can use it in the future for international travel. I'm trying to figure out the right steps.
Do I turn on the new phone and restore from iCloud backup first? Can I do that without first moving the old SIM over? Should I have the unlock code ready to go? I'm just confused about when to move the SIM over to the new phone.
I know that unlocking a phone requires you to erase the phone. Can I erase and just leave it at the Hello screen? Then just turn it off and store it? I'm trying to find these specific answers but no luck finding them.
Thanks in advance.
iPhone 6, iOS 12
