With just a few days to go until Mother’s Day, T-Mobile today revealed a new smartphone deal.

Starting Friday, May 11th, customers who buy an iPhone can get up to $700 back on a second iPhone. This deal is available to new and existing customers and applies to the iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, and iPhone X.

To get this deal, you’ll need to buy both iPhones on EIP and port in a line from a non-T-Mobile carrier. You’ll also need to pay any applicable down payment and taxes at the time of purchase and trade in a qualifying device. The list of qualifying devices looks like this:

Apple iPhone X, 8, 8 Plus, 7, 7Plus, 6s, 6s Plus, SE, 6, 6 Plus, 5s, Samsung Galaxy S8, GS8+, GS8 Active, GS7, GS7 edge, GS7 Active, GS4, GS5, GS6, GS6 edge, GS6 edge+, GS6 active, Note4, Note5, Note8, LG G6, LG V20, LG V30, LG V30+, LG G5, Pixel, Pixel XL, Pixel 2, Pixel 2 XL

Once you meet the requirements, you can go to T-Mobile’s promotions site and enter the promo code 18Q2APLBOGO and as well as your devices’ IMEI numbers. Within 6-8 weeks, you’ll get a prepaid MasterCard card worth up to $700. You’ll also receive the value of the trade-in device as a one-time store credit applicable towards your bill or other purchases.

If you’re looking for an accessory to go with your new iPhone, T-Mobile is also running a deal that’ll get you $215 off an Apple Watch or iPad when you buy any iPhone. This discount is applied via 24 monthly bill credits.

Finally, if Android is more your thing, T-Mobile is offering a deal that’ll let you buy an LG V30 or LG G6 and get a second one for free. Both phones must be purchased on EIP, but no trade-in or port-in is required.
