T-Mobile has been one of the world's best wireless carriers for many years now, offering extensive 5G coverage and a variety of data plans for every type of user (and every budget) under the sun. It's also home to a bounty of excellent Android deals at any given time, with thousands of dollars in savings up for grabs if you're on the hunt for a new phone.

I'm talking about offers that could get you the Galaxy S25 Plus for 100% free when you process a trade-in, or this deal that gets you a free Google Pixel 9a when you add an eligible line to your T-Mo account. Sure, they aren't exactly straight discounts, but if you're looking for a trade-in opportunity or an incentive to upgrade your data plan, there is no shortage of outstanding deals to explore.
