The FTC complains of a 2011-2014 practice in which AT&T throttled the speeds of unlimited-data users after they exceeded 3GB or 5GB, depending on the phone. AT&T now only slows down customers who exceed 22GB in a month and only when the network is congested.
“The Federal Trade Commission says it should be able to sue AT&T for throttling mobile broadband users, even though mobile broadband — which is now classified as a “common carrier” service — is no longer subject to FTC regulation.”
