Earlier this week, a U.S. District Court judge denied T-Mobile’s motion to dismiss a lawsuit filed by unhappy T-Mobile subscribers. The subscribers allege that the operator charges them for unsolicited text messages.

In the complaint, customers claimed they had no way to disable their phones from receiving text messages, often in the form of spam, and are forced to pay between 10 and 15 cents for every message.

In a statement from the operator, it said, “T-Mobile is committed to providing the best customer experience in wireless and does offer customers the ability to block chargeable text messages, MMS, IM and e-mail from being sent to their handsets at no additional charge. Customers can contact Customer Care or a retail sales representative for assistance and soon will be able to help themselves with tools on www.myt-mobile.com.”

The operator also said it has extensive filters built into the network to help detect and block spam text messages being sent to customers’ handsets, especially those that originate from Internet IP addresses. “These filters are updated on an ongoing basis, including monitoring for newly emerging schemes,” the operator wrote.

The case is scheduled to move ahead after clearly this first procedural motion.
