How do satellite phone Works

Did you ever thought that how satellite phone works.
How they make call when there is no network?
How they work in Mountain?
The working of satellite phone is is very simple.

When an individual makes a call from a satellite phone the signal is sent to the satellites of that particular company. These satellites process the call and relay it back to Earth via a gateway. The gateway then routes the call to its destination using the regular PSTN(Public switched Telephone Network).
Globalstar,Iridium are some of the company which provide satellite phone services.
NOTE**The Globalstar constellation is made up of 48 satellites and every call is relayed by up to 4 satellites down to Globalstar gateways on Earth.
So now don't worry of network problem.
