AT&T to Curb Wireless Browsing Speed for Heaviest Data Users

AT&T will curb browsing speeds for its heaviest users on unlimited wireless data plans to cope with surging data traffic.

Starting Oct. 1, customers on an unlimited plan whose monthly use puts them into the top 5 percent of data consumption may experience reduced speeds until the end of that billing cycle. Normal browsing speeds will return once the customer begins a new cycle.
