Wasn’t going to but ended up ordering an iPhone 16 Pro Max 256GB. Only had my iPhone 15 Pro for less than 12 months, but I fancied going back to the Max format. I bought the 15 pro on the 24 month 0% finance offer.
Cleverly, Apple will allow you to trade in the old phone and pay off the balance of the loan with a small adjustment. Then take out another 0% finance loan over 24 months for the new phone.
