T-Mobile US has announced that consumers' unused data each month now automatically rolls into a personal Data Stash so they can use it when needed for up to a year. Data Stash is included at no additional charge for new and existing T-Mobile customers on an eligible Simple Choice plan. In addition, T-Mobile announced it will start every Data Stash with 10 GB of LTE data for free.
Beginning in January 2015, Data Stash will be automatically available at no extra charge to T-Mobile customers with a postpaid Simple Choice plan who has purchased additional LTE data, 3GB or more for smartphones and 1GB or more for tablets. There is no limit to how much data a customer can collect in their Data Stash. Once a customer reaches their data plan limit, T-Mobile will automatically start using data from the customer's Data Stash.
