WASHINGTON — AT&T Inc. agreed to pay $105 million to settle claims that the company billed wireless customers for unauthorized charges for services including horoscopes, ring tones and love tips.

AT&T unlawfully billed customers for charges originated by other companies for subscriptions to the services, a practice known as mobile cramming, the Federal Trade Commission said in a statement Wednesday.

The FTC said $80 million of the settlement will be used for customer refunds to those billed for the unauthorized charges, while the remainder will pay state and federal fees and fines. Consumers can apply to the agency for refunds.

“This settlement will put tens of millions of dollars back in the pockets of consumers harmed by AT&T’s cramming of its mobile customers,” said FTC Chairwoman Edith Ramirez. “AT&T had strong reason to suspect that the charges were unauthorized, yet continued to place these charges on its customers’ bills.”

AT&T, the second-largest U.S. wireless carrier, is settling with the FTC, the Federal Communications Commission, all 50 states and the District of Columbia. The settlement was filed Wednesday along with a lawsuit in the U.S. District Court for the Northern District of Georgia.
