The Federal Trade Commission (FTC) filed a complaint against AT&T Mobility, claiming the company misled millions of smartphone customers by charging them for “unlimited” data plans while reducing their data speeds, in some cases by nearly 90 percent. The FTC alleged that the company failed to adequately inform unlimited data plan customers that, if they reach a certain amount of data use in a given billing cycle, AT&T reduces – or “throttles” – their data speeds to the point that many common mobile phone applications become difficult or nearly impossible to use. The FTC alleged that, in 2011, AT&T began throttling data speeds for its unlimited data plan customers after they used as little as 2 gigabytes of data in a billing period. The FTC claimed AT&T throttled at least 3.5 million unique customers a total of more than 25 million times. In August 2019 it was announced that the FTC and AT&T reached a settlement for an undisclosed amount. See related AT&T instance, “Misleading Consumers About Unlimited Data Plans”.
