AT&T confirmed to BGR that it will soon begin revoking unlimited data plans from jailbroken iPhone users and other smartphone users who utilize unauthorized tethering and mobile hotspot solutions. Following reports from earlier this year, AT&T on Thursday confirmed that it will remove grandfathered unlimited data plans from accounts belonging to users who tether or use unsanctioned mobile hotspot apps without a tethering plan, which is expressly prohibited by AT&T according to its terms and conditions. “Earlier this year, we began sending letters, emails, and text messages to a small number of smartphone customers who use their devices for tethering but aren’t on our required tethering plan. Our goal here is fairness for all of our customers,” an AT&T spokesperson told BGR via email. The letter outlines three choices for customers who had been making use of unauthorized tethering solutions, one of which is “Do nothing and we’ll go ahead and add the tethering plan on their behalf — after the dated noted in their customer notification.” According to earlier reports, offending users will automatically be bumped to AT&T’s more recent tiered data plan, which affords 2GB of smartphone data and 2GB of tethering data for $45 each month compared to AT&T’s old unlimited smartphone data plan, which costs $30 each month but does not include tethering. A new report from 9to5 Mac claims that users will begin losing unlimited plans as soon as August 11th, but AT&T stated that the policy enforcement date varies depending on when the offending subscriber was sent the notification letter. AT&T’s full statement follows below.

Earlier this year, we began sending letters, emails, and text messages to a small number of smartphone customers who use their devices for tethering but aren’t on our required tethering plan. Our goal here is fairness for all of our customers. (This impacts a only small percentage of our smartphone customer base.) The letters outline three choices: Stop tethering and keep their current plan (including grandfathered unlimited plan) Proactively call AT&T or visit our stores and move to the required tethering plan Do nothing and we’ll go ahead and add the tethering plan on their behalf — after the dated noted in their customer notification
