How can I swap my iphone 15
I have an iPhone 15 still having a limited warranty of 8 months, but I want to use it to swap iPhone 15pro max. How much will I add?
iPhone 15, iOS 18
Apple discontinued iPhone 15 Pro Max when iPhone 16 Pro Max was introduced. You can trade your iPhone 15 in to Apple and buy an iPhone 16 Pro Max paying the difference in the trade value and the cost of the new phone. But before you do that, if you owe anything on the phone by installments or to your carrier, you'll have to pay it off first.
