Preorders for Apple’s iPhone X start this Friday at 3AM ET, and we’re starting to see the first carrier deals for the upcoming smartphone. First up is Sprint, which will be offering a deal through its Sprint Flex leasing for $22.22 per month for 18 months with a trade in of an older device.

Like Sprint’s deals on the iPhone 8, though, it’s important to point out that the discounted price is only for the first 18 months. If you want to keep the phone outright, instead of trading in to Sprint for a new lease (which you can do after 12 months on the Sprint Flex lease), you’ll have to pay out the last six months at the full $41.62 per month (roughly) price. That said, at the end of the day, you’re getting a 64GB iPhone X — which retails for $999 — for around $649.68, which isn’t a bad deal (assuming you’re okay with giving up your old phone).

Sprint is also offering the deal to both current and new Sprint customers; the company only offered some of its iPhone 8 deals to new Sprint sign-ups.

If you’re interested in the deal, you’ll have to trade in a recent iPhone or Android device. The list includes: the iPhone 7 and 7 Plus, iPhone 6S and 6S Plus, iPhone 6 and 6 Plus, Samsung Galaxy S8 and S8 Plus, Samsung Galaxy S7 and S7 Edge, Samsung Note 5, LG G5, LG G6, LG V20, Google Pixel, Google Pixel XL, Moto Z Droid, Moto Z Play, Moto Z2 Force, Moto Z Force Droid, Moto Z2 Play, BlackBerry KeyOne, and the HTC U11.
