Verizon Wireless confirmed that in June it quietly stopped throttling the data speeds of customers who were on legacy unlimited data plans on 3G devices and who crossed into the top 5 percent of data users when they were on high-traffic cell sites.
AT&T has called a proposed $100 million fine levied against it by the FCC for alleged throttling "unprecedented and indefensible."
AT&T Mobility hit back hard against the FCC's proposed $100 million fine for not being transparent enough with its grandfathered unlimited data plan customers about how and when their speeds would be reduced if they use too much data. In its formal response to the agency, the carrier called the fine "unprecedented and indefensible" and said a court would toss it out if the FCC decided to levy the penalty.
Sprint quickly dropped a throttling limit on its new "All-In" data plans that limited streaming video to speeds of 600 Kbps after customers loudly complained about the policy.
T-Mobile US said its network management policy of throttling the speeds of smartphone customers on its unlimited LTE plans once they hit 21 GB of data usage in a month and are on congested cell sites is permitted under the FCC's net neutrality rules.
Sprint decided to end its practice of slowing down the data speeds of its heaviest mobile data users after the FCC's net neutrality rules went into effect last Friday. The decision is one of the first concrete impacts of the rules, which apply to wireless networks and bar data throttling except in cases of "reasonable network management."
The FCC is proposing to fine AT&T Mobility $100 million for not being transparent enough with its grandfathered unlimited data plan customers about how and when their speeds would be reduced if they use too much data. The fine is the largest the FCC has ever proposed.
AT&T Mobility asked a federal appeals court to decide whether the Federal Trade Commission can move ahead with a lawsuit that targeted the carrier's data throttling policies.
AT&T Mobility changed its data throttling policy, and will throttle the data speeds of customers on legacy unlimited data plans only when they are connected to congested cell sites, regardless of the kind of smartphone they have.
The FCC is set to vote on final net neutrality rules on Feb. 26, and T-Mobile US and the CTIA are urging the agency to give wireless carriers a great deal of flexibility in designing new service plans and business models.
