WASHINGTON (AP) -- AT&T is being sued by the government over allegations it misled millions of smartphone customers about its unlimited data plans.

The Federal Trade Commission says AT&T failed to adequately disclose to customers that it would reduce data speeds if they went over a certain amount of data use in a billing cycle. The practice, known as throttling, slows down things like web browsing, GPS navigation or watching streaming videos.
