SAN FRANCISCO — The Federal Trade Commission sued AT&T Mobility on Tuesday, claiming the company misled smartphone customers who have unlimited data plans. AT&T reduced speeds for some customers with unlimited data plans, in some instances by almost 90 percent, according to the FTC.
The lawsuit filed in the U.S. District Court for the Northern District of California claims that the company failed to adequately disclose that once customers with unlimited plans use a certain amount of data during a billing cycle, the company cuts data speeds leading to possible problems with activities such as web browsing, GPS navigation and streaming video.
