Last week, AT&T [hiked up rates](https://www.technobuffalo.com/att-raises-price-of-grandfathered-unlimited-data-plans-yet-again) on some of their unlimited “grandfathered” customers, the third increase in just the last two years. Those poor AT&T customers are now paying 50% more than originally. Quick, someone get AT&T execs a dictionary – that’s not how “grandfathering” works. Today, T-Mobile (NASDAQ: TMUS) is going to bat for those fed up AT&T customers. Starting Wednesday, June 20th, AT&T customers on their “grandfathered” Data Unlimited for iPhone on 4G LTE with Visual Voicemail plan can switch to T-Mobile, keep their number and get the Un-carrier’s WTH (Why the Hike) Deal – a $250 one-time offer to make up for AT&T breaking their promises over these last two years. And, that’s on top of up to $650 via trade-in credit and prepaid card with [Carrier Freedom](https://www.t-mobile.com/support/new-to-tmobile/carrier-freedom) to cover the cost of switching when you sign up for T-Mobile ONE…that’s up to $900 for upgrading to the Un-carrier. Plus, with T-Mobile’s Un-contract, only you have the power to change what you pay for T-Mobile ONE. “If there ever was any question, this seals it. AT&T is ‘Dumber’ for sure,” said John Legere, CEO at T-Mobile. “Here, let me explain the term “grandfathering” to you, Big Blue – it means keeping the same deal you got when you signed up. We won’t stop calling BS on the Duopoly when they screw their customers. That’s what the WTH Deal is all about. Righting wrongs is in our Un-carrier DNA.” ##### WTH (Why the Hike) Deal When your plan gets ‘grandfathered,’ it’s supposed to mean you’re locked in at that price. At T-Mobile, that’s just what you get with the Un-contract. Only you have the power to change what you pay for T-Mobile ONE. With the WTH Deal, anyone on AT&T’s “grandfathered” Data Unlimited for iPhone on 4G LTE with Visual Voicemail – and anyone who was on that plan through June 7th -- can port their number to T-Mobile AND get a one-time $250 deal via prepaid card. Plus, they can get in on any of the Un-carrier’s current [promotional deals](https://www.t-mobile.com/offers/deals-hub) for switchers and take full advantage of [Carrier Freedom](https://www.t-mobile.com/support/new-to-tmobile/carrier-freedom), for up to $650 via trade-in credit and prepaid card to pay off your contract or phone payments with trade-in when you sign up for T-Mobile ONE. For a limited time, visit a T-Mobile retail store or call 1-800-T-MOBILE and mention you’re joining from AT&T and want the WTH Deal. Then just port over a number from AT&T and add a qualifying T-Mobile voice plan – you will be asked to validate your eligibility upon activation. And with T-Mobile ONE, you’ll get a ton more than what your current AT&T basic Unlimited plan offers. With T-Mobile ONE, you’ll get unlimited LTE data on America’s best unlimited network, [Netflix included](https://www.t-mobile.com/news/tmobile-uncarrier-netflix) on family plans, free stuff every [T-Mobile Tuesday](https://www.t-mobile.com/offers/t-mobile-tuesdays) and taxes and fees included. And when traveling, you’ll get free texting all flight long and a free hour of smartphone Wi-Fi on Gogo-equipped domestic flights, plus free data roaming and texting in [140+ countries and destinations](https://www.t-mobile.com/coverage/roaming).
