|A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites. They provide similar functionality to regular cellular phones; voice, short messaging service and low-bandwidth internet access are supported through most systems.
Depending on the architecture of a particular system, coverage may include the entire Earth or only specific regions.
The mobile equipment, also known as a terminal, varies widely. Early satellite phone handsets had a size and weight comparable to that of a late-1980s or early-1990s mobile phone, but usually with a large retractable antenna. More recent satellite phones are similar in size to a regular mobile phone while some prototype satellite phones have no distinguishable difference from an ordinary smartphone. Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable.
A fixed installation, such as one used aboard a ship, may include large, rugged, rack-mounted electronics, and a steerable microwave antenna on the mast that automatically tracks the overhead satellites. Smaller installations using VoIP over a two-way satellite broadband service such as BGAN or VSAT bring the costs within the reach of leisure vessel owners. Internet service satellite phones have notoriously poor reception indoors, though it may be possible to get a consistent signal near a window or in the top floor of a building if the roof is sufficiently thin. The phones have connectors for external antennas that can be installed in vehicles and buildings.

There are four satellite phone network providers, Iridium, Inmarsat, Globalstar and Thuraya.
A fleet of 66 low-earth orbit (LEO) satellites provide military grade voice and data communications solutions with complete global coverage of the earth including polar regions. Iridium is the most reliable, and is the only network to cover all 7 continents.
The world’s leading mobile satellite operator. Its constellation of ten satellites located in geostationary orbit enables delivery of voice and high-speed data services and mobile IP broadband to almost anywhere on the planet. Inmarsat is a British company which offers excellent coverage along the worlds sea lanes.
Through its two geostationary satellites, Thuraya provides coverage of more than 140 countries in Europe and large parts of Africa and Asia for handheld voice and mobile IP broadband service. Thuraya is an innovative company based in the UAE and is a popular choice for Europe, Asia, Africa, and Australia. Sadly, coverage does not extend to the Americas.
Globalstar offers service in the Americas, Europe and parts of Africa and Asia. While phones and airtime rates seems attractive, actual service seems sporadic.
