Such information will also be transmitted through fiber optic cable in the form of light waves. Also it's doable to send such data in the form of radio-waves.
What is a Satellite phone ? A satellite telephone, satellite phone, or satphone is a mobile phone that communicates directly with orbiting communications satellites. Depending on the structure of a particular system, coverage may contain the entire Earth, or only specific regions. A Satellite phone is a unique instrument.
