If you're planning on traveling overseas this summer, you'll be able to catch up on all your shows and stay in touch with family without worrying about running out of data, just as you'll be given a free hour of Wi-Fi via Gogo domestic flights -- if they happen to offer it, that is. This offer extends even to Verizon and AT&T customers from June 24-26, so if you haven't quite been convinced that T-Mobile is the carrier for you after all this flash and showmanship, you can at least reap some of the benefits for the weekend.
T-Mobile has also announced that its customers will be able to roam without special charges in Belize going forward, so if that happens to be one of your destinations as you get away for vacation, you'll hopefully be paying significantly fewer fees, for that area of your trip at least.
T-Mobile is bent on proving its worth by giving its customers special rewards and promotions, though previously they were more focused on goodies and deals (even stocks) rather than expanding data or alleviating charges. It should be interesting to see where it aims next when it comes to pulling in customers.
