AT&T makes it official: Rollover Data is here

"Rollover Data is an added benefit of being an AT&T Mobile Share Value customer and it’s just another way that we’re saying thanks to our more than 50 million plus Mobile Share Value subscribers. We’re providing even more value and flexibility, and the best part is it’s simple, shareable and easy to track for our customers. All Mobile Share Value customers get this automatically."-Glenn Lurie, President and CEO, AT&T Mobility
With AT&T offering Rollover Data, the question becomes whether this will become an industry wide innovation that eventually makes it to all four major carriers. We also have to tip our hat to T-Mobile CEO John Legere. As we pointed out in our exclusive this morning, the executive made a list of predictions for 2015. One of his "calls" was that AT&T would offer its own version of Data Stash which it has now officially done.
