T-Mobile is still pushing hard on its “Un-carrier” campaign, and their newest venture is a huge boon to baseball fans. T-Mobile and MLB have extended their partnership another three years. This means a lot of T-Mobile branding will be seen on various MLB properties — including things like the All Star Game — but the “celebration” of the partnership brings some big-time savings.

Any T-Mobile customer on the Simple Choice plan will have the opportunity to sign up for a free year of MLB.tv. And from what I’m reading, that doesn’t really include a lot of red tape or hoops to jump through. There is one slight catch, however. The deal isn’t available until April 3rd. This is all well and good for the start of the season, but not so much if one is interested in streaming Spring Training games. To counteract that slight bummer, T-Mobile and MLB are sweetening the pot a little.

The free subscription also comes with complimentary access to the MLB At Bat Premium so that users can get all the additional features of At Bat on their smartphones and tablets. The inclusion of the app usually comes with MLB.tv regardless, but it’s nice to know that there won’t be any sneaky gotchas after signing up.

Also, MLB.tv qualifies for T-Mobile’s (somewhat controversial) Bing On program, wherein customers can stream MLB.tv (along with many other video services) via their cellular connections without it counting toward their plan’s data allotment. T-Mobile customers are free to watch games on the bus, in church, during work, or anywhere else they don’t have access to WiFi without worry of data overages.

The kicker to the deal is that a user’s MLB.tv subscription will be valid for any device, not just their T-Mobile phone. This means fans can still watch on their smart TVs, gaming consoles, or other connected devices using their MLB account. This is a nice pivot from other offerings like Verizon’s NFL package, which allows fans to watch certain NFL content (mainly Red Zone) for free, but only via their Verizon device. T-Mobile’s deal will let people watch via their PlayStation or Roku with no extra strings and, theoretically, they’ll never have to even watch on their phones if they don’t want to.

MLB has seen some big changes recently in terms of their MLB.tv offering. It’s hard to say whether this T-Mobile partnership is an extension of that or not, but it’s certainly a nice added bonus. There are some lingering questions, however. If I purchased MLB.tv already, can I cancel and sign on via T-Mobile? If I cancel my T-Mobile account, does my MLB.tv go away? Details on this are fuzzy right now, so it might be best to stop into a store or call T-Mobile yourself to get the best answers.

Wireless providers are pulling out all the stops these days to convince customers to switch, and if a baseball fan were shopping around for a new carrier, this might be the very thing that puts them over. I doubt the offer will be good next year, but for current T-Mobile customers or people who were already looking to switch, saving over $100 is always a good way to start the season.
