Since you moved your sim from your 12 to 13 pro you will not be charged. I moved my sim from 12 pro max to 13 pro max and there weren’t a charge and have always done this route in the past.Will Verizon charge me an upgrade fee? My iPhone 13 Pro is unlocked from Apple and all I did to activate was remove the sim from my iPhone 12 and put it in my 13 pro. my phone is fully activated on VZW but I didn’t get any message that I would be charged a fee.
