T-Mobile, Cingular Team On Multimedia Messaging

T-Mobile USA and Cingular Wireless said Thursday that they will enable users of one carrier to send and receive multimedia messaging service (MMS) messages from the other.

The two carriers are the only ones in the U.S. that use GSM-based systems. MMS messages can include text, images, video or audio.

"People want to expand their world of communications by allowing more people -- including those with different wireless providers -- to receive their text, instant and picture messages," Michael Gallelli, T-Mobile's director of product management, said in a statement.

T-Mobile USA is owned by Germany's Deutsche Telekom. Recent unverified reports have said that the German company is considering selling its U.S. unit.
