T-Mobile says starting July 19 customers will be able to play Pokemon Go on their smartphone without impacting their monthly data allotment. T-Mobile is adding Pokemon Go to its T-Mobile Tuesday customer appreciation program. Customers will need to take action to get the free Pokemon data. First, customers need to download the T-Mobile Tuesdays app from the Google Play Store or iTunes App Store. Once signed in, customers can claim the free zero-rated use of Pokemon on T-Mobile Tuesdays July 19, July 26, August 2, and August 9. Once claimed, Pokemon usage will not touch customers' high-speed data plan through August 2017. The zero-rated Pokemon promo is only available to claim for the next four Tuesdays and goes away after August 9. Beyond the Pokemon promo, on Tuesday, July 19 T-Mobile customers can claim a free Lyft ride of up $15, a free Frosty at Wendy's, and 50% off select accessories. Last, T-Mobile says 250 people will win $100 in PokeCoins, and five people will win a Pokemon Go hunting trip for two anywhere in the U.S.
