The iPhone 18 Pro and Pro Max are now official and T-Mobile is celebrating the launch of Apple’s new phone releases with “On Us” deals that are hard to pass!

That’s right, for a limited time during the iPhone 18 Pro’s launch period, T-Mobile is running an “up to $1,200 off on any iPhone 18 Pro” campaign. That’s the full price of the 256 GB iPhone 18 Pro, or a significant chunk out of the iPhone 18 Pro Max’s price.

How the T-Mobile iPhone 18 Pro deal works

There are two ways to get this deal — both new customers and existing T-Mobile subscribers are eligible!

For new customers, activate a new line and port in a number on Experience Beyond 2.0, Experience Beyond, or Go5G Next. You will save up to $1,200 on a new iPhone 18 Pro or iPhone 18 Pro Max — the discount is applied via bill credits over up to 36 months.[1]

Existing customers in good standing can also make use of the “On Us” offer. They need to be on any Experience Beyond plan — or switch to one — and trade-in an eligible device in any condition. Their $1,200 discount will be applied via bill credits over up to 36 months.

This easily puts T-Mobile’s offers among the best carrier deals for the iPhone 18 Pro and iPhone 18 Pro Max during the launch period.

Apple’s iPhone 18 Pro comes with the A20 Pro — Apple’s first 2nm processor, which is faster and more energy-efficient than before. They paired that with a larger battery than before to enhance the phone’s endurance further, and an upgraded vapor chamber for even more sustained performance.

The cameras have also been updated, with the first-ever variable aperture on an iPhone (F1.4 to F4.0), 48 MP sensors for the main, ultra-wide, and telephoto cameras, and a new Pro mode to let enthusiasts get full control over the imagery.

Is T-Mobile a good network in 2026?

For the past two years, T-Mobile has been ranked “Best overall network” by independent speedtester Ookla[2].

There are plenty of good reasons to switch to T-Mobile’s Experience Beyond 2.0. Incredible entertainment benefits, including a Netflix Standard subscription, Hulu, and even a reduced price on Apple TV+. Included benefits such as roadside assistance and “DoorDash On Us”, which lowers or removes service fees and delivery fees.

And that is, of course, on top of unlimited premium mobile data, up to 4K UHD video streaming (on 5G), unlimited hotspot use, unlimited text and 30GB of data in Mexico and Canada, unlimited text and 15GB of high-speed data in 215+ countries & destinations.
