Another reason to thank T-Mobile. AT&T rollover only rolls over to the next month rather than a year like T-Mobile but at least you get some extra data the next month.
HERES HOW IT WORKS: All levels of AT&T Mobile Share Value plan customers automatically receive the Rollover Data feature no signing up, no additional cost.
Rollover Data can be shared with everyone on the same Mobile Share Value plan. If you do not use your full allotment of plan data in a given month, the extra amount automatically rolls over and is available to be used within the next month.
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.
