Trade in
Hello. I want to trade in my iPhone 13 about which I have had on credit for 13 months, I have 11 months left to pay and I will finish the payment. If I trade in for 15 pro Max, then when I trade in I need to pay for 13 pro in full and then only change to 15 pro Max. Or can I take 15 pro Max on credit and they will sum up the loan for 15 pro Max and 13 pro and pay together?
iPhone 13 Pro, iOS 16
