September is unofficially “iPhone Month” at T-Mobile, and the Un-carrier has two screaming deals for anyone who wants to get their hands on Apple’s latest superphone on the fastest 4G LTE network in the country:

Get your new iPhone 7 on us! Starting September 9 at 12:01am PT, all new and current T-Mobile customers can pre-order a new iPhone 7 32GB and get it on us when you trade in your iPhone 6 or newer model (any memory variant). Want a different model or more memory? Just pay a little more upfront – it’s only $120 to upgrade to iPhone 7 Plus 32GB, and each memory increase is an additional $100.

The mechanics are simple – when you trade in your current iPhone 6, 6 Plus, 6s or 6s Plus, you’ll see a monthly credit on your T-Mobile bill. After 24 months, you’ll have paid nothing and will owe nothing on your iPhone 7 32GB. To be eligible for this promotion, you’ll need to own your trade in device outright – in other words, you can’t still be making payments on it – and it needs to turn on, not have water damage, and the screen can’t be shattered.

Here’s a new chart to help illustrate this super sweet deal.

Sign up for T-Mobile ONE and get the 4th line free! To celebrate the awesome new iPhone 7 and 7 Plus – and for families that don’t want limits – we’re kicking off a new T-Mobile ONE deal. Available now for a limited time, families of four can get T-Mobile ONE and get the 4th line free. That’s just $140 for a family of four – just $35 a line (phone or tablet) with autopay – for unlimited everything including talk, text, standard-def video and high-speed data on America’s fastest LTE network.

Anyone looking to get in on either of these amazing deals can sign up at participating T-Mobile stores nationwide, by calling Care (611 or 1-800-937-8997) or by visiting us online – for more info on iPhone at T-Mobile, visit www.t-mobile.com/apple, and visit www.t-mobile.com/tmobileone for info on the new T-Mobile ONE promotion.
