According to FierceWireless, AT&T has confirmed that it may throttle their heaviest data users or top 5% in a given billing period. While unlimited data users will still remain unaffected from a price standpoint, they will likely be throttled down to 2G speed levels.
According to the carrier, the new policy will affect a “very small minority” of subscribers who use an “extraordinary” amount of data. “In fact, these customers on average use 12 times more data than the average of all other smartphone data customers.
It was not announced what level of data the tethering will begin at outside of the 5% number but it was however noted that customers would be evaluated on a month-by-month basis.
