T-Mobile kicked off a Buy One, Get One deal on Apple, Samsung, and LG smartphones last month, but the Apple phones were only part of the deal for a little more than a week. If you missed out on that offer, you’re going to get a second chance.

From December 21st through December 24th, T-Mobile will bring back two of its previous iPhone offers. You’ll be able to buy an iPhone 7, iPhone 7 Plus, iPhone 8, or iPhone 8 Plus and get a second one for free.

As with the previous deal, you’ll need to add a new line and buy both iPhones on EIP to get this deal. Once you do, you’ll get a prepaid MasterCard card to cover the cost of the cheaper device. This offer covers up to $700 for the second device, which means that customers that opt for two iPhone 8 Plus models will pay $99.99 for their second device.

If you prefer the iPhone X, T-Mobile’s bringing back a deal for you, too. You can get up to $300 off an iPhone X after trading in a qualifying iPhone and buying the iPhone X on EIP. The devices that qualify for trade-in are the iPhone 6 and newer (with the exception of the iPhone SE).

These deals will be available in store and online starting tomorrow, December 21st, and they’ll be valid until end of day on Sunday, December 24th.
