AT&T customers with an existing line can apply for the Special Carrier Deal.
After receiving the trade-in package, you have 14 calendar days to prepare your device for return. If you ordered an iPhone with a trade-in, the kit will be included with your new device. You will receive the kit separately once your new product arrives. Your trade-in will become complete once we have received it. If your device isn't in the same condition as you described, we will send you an email detailing next steps. If you paid full price and the device's worth was greater than the purchase price, you will receive an Apple Gift Card email with the remainder.
Unfortunately, if you go unlocked, you can only pick up a new Apple device directly. Apple does have its iPhone 13 Pro Max deals available, including a rebate of up $650 for trade-ins. It's not the most expensive on the market but it does cut down a lot of the cost. You can't go wrong with an unlocked device, especially if you need plan flexibility. Total cost: $449 (maximum Savings)
