AT&T recently launched new a unlimited data plan, but as with most other carriers, AT&T’s plan has a usage threshold after which point your data will be deprioritized. Now that threshold is being applied to tablet customers, too.
AT&T is contacting customers with grandfathered unlimited tablet data plans to alert them to a policy change. Starting on May 24, 2017, customers with unlimited tablet data plans will be subject to data deprioritization once they use more than 22GB of data in a single month.
