What is a Satellite Phone?

A satellite phone as indicated by its name totally relies on satellite. It is a mobile phone that connects to the satellite which is revolving in the earth’s orbit. It does not need big towers or line of sight communication. A single satellite can provide communication over the big area of the earth. It contains antenna at the top of the phone for taking a signal strength from satellite. A satellite phone can connect anywhere as long as it is covered by the satellite beam. Buildings, trees, and other things can obstruct the signal strength of satellite phones. It provides us the service of SMS, Internet, Calls same as the cellular phones.

How satellite makes a Phone Call?

Satellite phones communicate directly with the satellite which is present in the Earth orbit. We can even make a call from earth planet to Mars planet. This process done in 3 steps

  1. While making a call signals from the satellite phones, the signal transmitted directly to the satellite.
  2. The satellite sends this signal to the nearest land-based earth station.
  3. The Earth station transmits the signal to the receiving phone. The receiving phone can be a landline, cell phone or another satellite phone.


All satellite phones are considered as international calls. assigned a 9 digit international telephone number along with a 3 digit Country Code.
