A satellite phone is effectively a mobilephone which uses satellites for communication, rather than cell like standard mobile phones. There are three satellite phone networks that are currently in operation:
•Iridium
•Globalstar
•Thuraya Iridium
The Iridium network uses 66 low earth orbit satellites in polar orbits 485 miles above sea level. The use of low earth orbit satellites helps minimize round-trip-time, which greatly improves the perceived quality of the phone call. The Iridum network is able to provide complete global coverage. There is no where on Earth where you can't receive a satellite phone call over the Iridium network.
Thuraya
The Thuraya satellite phone network provides coverage over Europe, the Middle East, Central and Northern Africa, Central Asia and the Indian subcontinent.
Thuraya offers dual-mode GSM and satellite mobile telephone services, transmitting and receiving calls through each satellite's 12.25-meter-aperture reflector.
The Thuraya geostationary satellites utilize on-board digital signal processing to create more than 200 spot beams that can be redirected on-orbit, allowing the satellite phone network to adapt to customer demand in real time.
Satellite phone calls are routed directly from one handheld unit to another, or to a terrestrial network.
The Thuraya network has the capacity for 13,750 simultaneous voice circuits.
Globalstar
The Globalstar network utilizes 40 low earth orbit satellites orbiting at an altitude of 876 miles.
The Globalstar satellite phone network provides coverage over most of the Earths land mass. This includes most of North and South America, Europe, the Middle East, Northern Asia, and Australia.

Advice on hiring Satellite Phones
Rental and hire of satellite phone solutions has greatly increased over the last eight years. The requirement has been from people and businesses traveling to areas outside of cell and landline coverage who want the peace of mind that in a crisis they can get help with a simple phone call. They also want the ability to stay in touch with friends, business partners, associates and family
How do you find a satellite phone to rent?
In most cases you will not be able to run down to the local cellular store and pick one up and if you call them they will most likely tell you "There is no such thing as a handheld satellite phone". Most people find satellite phones on the Internet which can be shipped to their home or business to arrive on a certain desired delivery date. Satellite phones can often be rented by the week or by the month. The fees can vary depending on the time of year. Be careful some satellite phone providers will have hidden fees like daily minimum usage fees which can substantially increase the cost of your rental. If the user plans to only use the phone in a crisis they can choose the flat rate per minute a pay-as-you go option. If the rental customer plans to use the phone more they can choose a number of prepaid bundled minute plans offered by GlobalCom which are discounted. Numerous optional accessories are available including data kits allowing you access to the Internet using a PC. Other options include cigarette lighter adapters, solar panels, water-proof cases, leather cases, extra batteries and more. GlobalCom currently recommends the Iridium rental unit which provides un-paralleled planetary coverage with their constellation of 66 satellites.
