TMobile announced a new program Data Stash that will allow you to rollover you unused monthly data and store it for 12 months. Why not call it rollover? AT&T actually owns the use of the term "rollover" from its days when it rolled over minutes as Cingular Wireless. John Legere said: "Can you imagine your gas station siphoning unused gas from your car each month? The US wireless industry is even worse," said John Legere, president and CEO for T-Mobile. "Americans have been gamed by the carriers into buying huge data plans – all to avoid getting screwed with overage penalties. Only to find out they bought more than they need which is then confiscated by the carrier. For the consumer it’s lose, lose." "That data is rightfully yours," added Legere. "And, we’re putting an end to this appalling industry practice today. With Data Stash, when you buy additional high-speed data, there’s no need to lose what you don’t use." TMO wants your business and has launched some very aggressive programs recently. Go ahead – Keep the data that’s yours Head over to the TMO site for the scoop.
