The Federal Trade Commission today filed suit against T-Mobile saying that T-Mobile made "hundreds of millions of dollars" by charging customers for premium SMS subscriptions.

the FTC said that when customers complained, T-Mobile continued to bill some users for years. The charges, which ran $9.99 per month, were for such things as flirting tips, horoscope information, or celebrity gossip, which was charged to customers accounts by scammers without the customer's authorization.

FTC Consumer Protection Director Jessica Rich said: "T-Mobile knew about these fraudulent charges and failed to take any action."

FTC Chairwoman Edith Ramirez said in a statement: "It's wrong for a company like T-Mobile to profit from scams against its customers when there were clear warning signs the charges it was imposing were fraudulent. The FTC's goal is to ensure that T-Mobile repays all its customers for these crammed charges."

T-Mobile did not immediately respond to a request for comment.
