Today, the company announced that starting January 25th, any AT&T customers in the Mobile Share Value system will be able to carry over unusued data to the next month.
I’m still holding onto my unlimited data plan from years ago, but this is the kind of announcement that might convince me to rethink that decision. Having the ability to bank unused data will help keep you from incurring overage fees during months with more heavy usage. This is a step in the right direction.
