T-Mobile has unveiled a new service called Data Stash, which lets customers roll over unused 4G LTE data from month to month.

Data Stash will roll out to all customers on eligible T-Mobile Simple Choice Plans starting in January, and every customer starts off with 10GB of free data for each line on their plan.

T-Mobile already offers unlimited data for all customers, so what exactly are you rolling over? High-speed data. Customers typically buy a bucket of gigabytes of 4G LTE data. Once you hit that cap, the company throttles your internet connection to a slower 2G speed.

This doesn’t apply to folks who pay extra for T-Mobile’s Unlimited 4G plans.

T-Mobile CEO John Legere says the average customer pays for 4GB or 5GB of data each month, but uses less than half. Data Stash will let customers roll over unused data for use in later months… which could let you sign up for a cheaper plan if you occasionally expect to need a lot of data, but don’t think you’ll need it every month.

Unused data can be rolled over for up to a year.

Data Stash will be available with any T-Mobile Simple Choice Plan that includes 3GB of data or more.

  1. Well Tmobile has horrible coverage (2g) in my area so I won’t be switching. However, I hope AT&T and other carriers follow. I always said AT&T should do rollover data, they always made a big deal over rollover minutes. I never even go over 10gb on mobile share, have 2 flip phones and 3 smartphones on it. Recently switched to 15gb plan for same price when they did promotional offer.
    Well last time tmobile made a new plan, att announced there new mobile share value plans and my bill went from $250 to $180 (with taxes). Keep up the good work tmobile! I love lower prices!
    Now if prepaid carriers like cricket could add mobile hotspot on all there plans…

  2. C Spire introduced rolling data a few weeks ago, so T Mobile is actually not the first.

  3. Data plan BS is BS.
    -and don’t tell me what I can do with my data either because it doesn’t matter if I’m on YouTube or creating a hot spot for others.
    My data, my call. It doesn’t matter how is used.

  4. Ive seen Liliputing state several times that T-Mobile has Unlimited Data that is throttled for 4g service after a specific threshold is met.

    This is incorrect. I have been on an true unlimited plan with T-Mobile for over a year now, and they do NOT throttle any longer. I have hit upwards of 13gb, and not had issues with being throttled.

    What they do have is unlimited data (throttled) on non-unlimited plans. So say you have 2gb of data every month. Once you hit 2gb then you are kicked to 2g service.

    So rollover IS important as people like my mother who never hit her 2gb limit, will start pooling up data.

    1. True… but then Data Stash doesn’t really affect people who have the most expensive plans. It’s aimed at people on cheaper plans.

    2. Brad is obviously talking about unlimited plans with 4g data cap which you do not have.

    3. *Up to* 2G speeds, actually. It’s usually a little slower, and in some cases as low as 50k in testing. If you google around, you can find quite a few different posts about how miserably slow their throttled quote-2G-unquote speeds are.

    4. T-Mobile calls all their plans “unlimited.” Even the non-unlimited ones…
