T-Mobile Unveils New 'Data Stash' Program That Allows Unused Data to Roll Over Each Month

As part of its new Un-carrier 8.0 announcement, T-Mobile today unveiled its new "Data Stash" program that allows consumers to roll over their monthly unused data. At the end of the month, consumers will be able to store their unused data without limit for the next 12 months.

"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."

To kick start the program, T-Mobile will provide 10GB of free 4G LTE data to customers as a starting stash. This free 10GB data stash is not shared, but will be allotted to each line in a family or business plan. The new Data Stash program will be available starting in January 2015 and will be applied to every individual, family and business plan automatically.

I applaud it.

T-Mobile is where it's at right now.

It's the best carrier right now.

Agreed. This CEO is on the exotic side but I like his style. Verizon and AT&T are just theiving and he is calling it out and coming in strong. If they can make their network as big as Verizon or AT&T and posing threats to them, it will be good for everyone.

This is a no-brainer because it won't put any additional stress on their network. Until I switched plans at ATT last week my wife and I had an old family plan with 1400 minutes. We rarely used them all and regularly had between 3,000 and 4,000 minutes rolled over. Did that cause us to somehow panic and decide that we needed to make a bunch of calls, nope! People's data usage habits are just that, habits. It's highly unlikely that someone or some family who regularly use less than all their data and then have it rolled over will run out towards the end of 12 months and suddenly use it all. Sure it's handy to have if you go on vacation somewhere where there isn't wifi and suddenly your usage pattern changes for a week or two but my guess is this is a great marketing move with little overall impact to their network. Nice job T-Mobile!

Unfortunately, T-Mobile has the spottiest service of all the major carriers. If they can build their 4G system out so they have more and better coverage, they will be able to put real pressure on the big 2. As it sits, half the places I use service, T-Mobile gets zero bars.
