Every time I try to upgrade to iPhone 15 or the pro or plus or max. It always says item out of stock. But if I change the color then my monthly payments goes away and it wants full retail price. I have had my iPhone 13 for over a year and it’s paid off. It tells me my device is 100% upgradable. I don’t understand why it’s so difficult to upgrade. I’m thinking about jumping on my wife’s plan through atat and get iPhone 15.
