T-Mobile may claim that it always has its customers best interests at heart, but the US government thinks otherwise. According to the FTC, T-Mobile commonly adds charges for premium SMS-based subscriptions for services like flirting tips, horoscope information or celebrity gossip that typically cost $9.99 per month. Furthermore, the FTC is claiming that T-Mobile did nothing to stop these charges for years after it signs showed the services were spam. The suit also alleges that T-Mobile commonly claimed that customers had authorized the charges without providing any proof.
