T-Mobile is not only the fastest-growing of the big three carriers, it’s also the most affordable of the big three. That said, the gap isn’t as big as it used to be, but the good news is that there are plenty of solid T-Mobile deals that can still make it worth the switch. Whether you’re a new or existing customer, you’ll find trade-in offers, free device promos, and even occasionally free or heavily discounted lines.
Below, we’ve rounded up the top promotions available heading into October of 2025 for phones, tablets, and smartwatches. While many of these offers might be similar to last month’s promotions, there are a few changes, including better offers on the iPhone 17 and a few other shifts.
The best T-Mobile deals at a glance
Get the iPhone 17 or iPhone 17 Air for free without any trade-in required
Right now, you can get the recently released iPhone 17 and 17 Air for free without any trade-in, for those switching to T-Mobile on an Experience Beyond, Experience More, or Go5G Next plan. Those interested in the iPhone 17 Pro or Pro Max might not be able to get it for free without a trade, but you can still get it for up to $1,000 off.
Already with T-Mobile? You can still get the phone for free with a trade-in, regardless of the device’s condition. The only catch is you’ll need to be on Experience Beyond or Go5G. For those on cheaper plans, you can still get the same offer, but only if you’re trading in and also adding a new line.
