U.S. sues T-Mobile USA, alleges cramming of bogus charges on bills

U.S. authorities filed a complaint against T-Mobile USA on Tuesday, accusing the wireless provider of adding millions of dollars of unauthorized charges on to customers' bills, a practice known as cramming, according to Fox Business.

The charges were for subscriptions to services such as horoscopes or celebrity gossip text messages, which often cost as much as $9.99 per month. T-Mobile USA received 35 to 40 percent of the amount charged, the Federal Trade Commission says.
