The Tok'ra use a small hand-held device to communicate over distance. The Tok'ra communicator was designed to transmit from within Tok'ra tunnels and has a range sufficient to reach a ship in orbit. The SGC has acquired several of the Tok'ra communication devices, and they have especially been used on missions when communication between an orbiting ship and a planet's surface is required.
