T-Mobile’s 5G now calls strikes in MLB, but this freebie might be the real highlight

T-Mobile recently announced that with Major League Soccer’s (MLS) 30th season kicking off, customers can stream all the action for free, no matter where they are. But soccer isn’t the only sport on the list – Major League Baseball (MLB) is included, too.

As MLB’s official wireless partner, T-Mobile is taking things up a notch by powering the league’s new automated ball-strike system (ABS) with its private 5G Advanced Network Solution (ANS). This marks the first time the tech is being used at the major league level, debuting during spring training games at Steinbrenner Field in Tampa, Florida.

And that’s not all – T-Mobile is also bringing back one of its most popular perks: free MLB.TV. Starting March 25, just in time for Opening Day, customers can once again stream live baseball at no extra cost.


T-Mobile is taking its 5G-powered ABS system to the big leagues after putting it to the test in minor league games and at the All-Star Futures Game. This system uses Hawk-Eye cameras around the stadium to track each player’s strike zone, and when the pitch is thrown, T-Mobile’s private 5G network quickly sends the data to verify where the ball landed. The result? A quicker, more secure pitch location check.

T-Mobile says its private 5G network delivers a super-fast, low-latency connection, making real-time communication with the ABS system seamless – whether it’s reviewing calls, analyzing pitches, or relaying decisions to players and fans.

The Un-carrier has been busy expanding its 5G network, rolling out private 5G setups in 27 MLB ballparks so far. By the end of 2025, T-Mobile plans to have its network in every MLB stadium across the US.

And finally, T-Mobile is bringing back one of its fan-favorite perks – a free season-long MLB.TV subscription, otherwise worth $149.99. From March 25 to March 31, eligible T-Mobile, Metro by T-Mobile, Home Internet, and Small Business customers can grab the free subscription through T-Mobile Tuesdays in the T-Life app.

And speaking of the app, earlier this month, T-Mobile officially retired its original app, replacing it with the T-Life app. However, the new app hasn’t exactly won over everyone. In fact, it’s been so unpopular with some users that they have even considered leaving the carrier or have already jumped ship.
