US Cellular has introduced SpeedTalk, a new push-to-talk service, for Kyocera Model KX440 and LG model UX4750 handsets.

SpeedTalk operates on the carrier's all-digital network and allows simultaneous communications within groups ranging from 2 to 20 people. Calls can be switched from a handset’s speakerphone to an ear piece or hands-free attachment for greater privacy. Group members can be added via the handset or a Web interface at
