T-Mobile guarantees the best trade-in price on your used mobile devices

T-Mobile today announced the US carrier will be guaranteeing the best trade-in prices for customers. The company aims to best AT&T, Sprint and Verizon by offering $50, as well as the difference back, if consumers find a better deal elsewhere. It's for a limited time only and kicks off on September 17. T-Mobile will monitor the market and adjust trade-in prices accordingly.

If you happen to find a better deal after trading in with T-Mobile, all one has to do is contact the carrier and confirm details as to where, when and for how much the better deal was for that particular device. $50 will then be rebated as credit on the account. It's a neat deal for anyone looking to upgrade with the network.

Bellevue, Washington – September 8, 2014 – In advance of a huge wave of new superphones and tablets coming to market this fall, T-Mobile (NYSE: TMUS) today vowed to beat the big carriers' best trade-in values on used devices - to help American wireless consumers get the very best deal on the hottest new devices.

Consumers can now have peace of mind when they're ready to upgrade, knowing that their trade-in at T-Mobile is the best deal they'll find anywhere compared to AT&T, Sprint and Verizon. And, they'll never have to worry about the fine print and all the details the carriers continue to hide behind.

"We're going to see some of the most phenomenal devices ever in the coming months, and that means a whole lot of Americans trading-in their devices and upgrading," said John Legere, president and CEO of T-Mobile. "For years, the big carriers have been ripping off their customers with low-ball trade-in values, so we're putting an end to that and guaranteeing we'll give customers what they deserve − the best value in the industry."

This latest move is just one more example of T-Mobile changing the way consumers buy wireless service and innovating ways to give everyone the best access to the most amazing technologies of our lifetime.

"When that new superphone's price is the same everywhere you go, the difference in your final cost comes down to the trade-in value of your old phone," said Mike Sievert, chief marketing officer for T-Mobile. "Now when you're ready to upgrade – it's a no brainer where to find the best value– the Un-carrier. Guaranteed."

To make good on this guarantee, T-Mobile will track the market every day to ensure we keep our promise. If a customer can find a better trade-in offer from a major national carrier, T-Mobile will beat that offer, give them the difference back and because we value this help from our customer we will top it off with another $50!

This offer starts September 17 and is for a limited time. All a customer has to do is call T-Mobile or go online within seven days of completing a trade-in at T-Mobile and tell us where, when and for how much they saw a better deal for their device. It's that easy.

Eligible device trade-in, qualifying credit, and new device purchase with qualifying service required. Difference in trade-in price and $50 offer applied as a bill credit within 2-3 bill cycles. See T-Mobile.com for details.
