The Federal Communications Commission said Wednesday it plans to fine AT&T Mobility $100 million for misleading customers about its "unlimited" mobile data plans, imposing the agency's largest proposed fine ever in alleging that the carrier "severely" slowed down the data speeds for customers with such plans.
AT&T failed to adequately notify its customers that they could receive speeds slower than the normal network speeds AT&T advertised, the FCC said. AT&T's actions also violated the FCC's 2010 Open Internet Order, commonly called net neutrality rules, the agency said.
