Some former AT&T customers are eligible for a refund from the company, the Federal Trade Commission announced.

The refunds are the result of a settlement with AT&T over allegations it reduced data speeds on unlimited accounts – a process known as data throttling – effectively slowing down internet speeds after certain amounts of data was used in billing cycle.

“After customers used a certain amount of data in a billing cycle, they experienced data speeds so slow that many common activities like web browsing and video streaming were difficult or impossible,” AT&T said.

As part of the settlement, AT&T agreed to pay $52 million to current and former customers. Current AT&T customers received their portion of the settlement in the form of a bill credit in 2020 but former customers are now eligible to receive their part.

To be eligible, you must be a former AT&T customer who had an unlimited data plan at some point between Oct. 1, 2022 and June 30, 2015 and experienced slow data speeds. You cannot have previously received a payment from AT&T in this matter to qualify.

The amount of payment will depend on how many people apply and there’s no schedule yet as to when the payments will be made.
