AT&T today responded to T-Mobile's recently launched Data Stash feature by introducing Rollover Data. According to AT&T, Rollover Data is available to all its Mobile Share Value plans users, which represent the majority of its customers. AT&T's Data Rollover program will carry unused data over for one month. For example, if a customer with a 10GB Mobile Share Value plan uses only 5GB in a month, the unused 5GB portion will roll over to the next month, giving them a total of 15GB of access. If that customer uses 5GB again, they'll carry over only the unused 5GB portion of their original allotment, not the enlarged amount. AT&T says, "Within a given month, you will use your plan allotment first, before you begin using your Rollover Data. Unused Rollover Data does not carry over." The Rolled Over data is available to all the members of Mobile Share Value plans to use. AT&T Mobile Share Value customers will be able to view their Rollover Data balance on the myAT&T app or online. AT&T's Rollover Data program begins January 25. All Mobile Share Value plan subscribers will be automatically enrolled at no additional cost.
