If you’re looking to upgrade your phone, T-Mobile back-to-school deals offer some fantastic deals at the moment that could net you a flagship smartphone like the iPhone 15 pro or Samsung Galaxy S24 for free if you trade in your old device.

Smartphones are expensive, and with new models released every year, it can be tough to keep up with the current tech without putting a major hole in your wallet.

Fortunately, phone carriers in the U.S. offer upgrade paths, letting you trade in your old handset for the latest model at a hefty discount. T-Mobile is one such provider, and their latest round of back-to-school offers can net you some of the best smartphones of 2024 including the iPhone 15, iPhone 15 Pro, Samsung Galaxy S24, and Google Pixel 8.

If you don’t need a top-of-the-line phone, they’ve also got some great offers on some cheaper handsets like the Samsung Galaxy A15, and the older iPhone 14 — it might be last year’s model but it’s still a fantastic phone today.

Most of these deals will require you to trade in your old handset, and all of them will require you to either sign up for a new T-Mobile plan or have an existing plan with them. And if none of these strike your fancy, check out our best phone deals page for more great offers on handsets.

Here's what T-Mobile's back-to-school deals have to offer:
