Iridium satellite phones, produced by Iridium, the company is one the leading providers of satellite communication in the world. Motorola In 1997 launched the very first low earth orbit (LEO) satellite network, to supply handheld satellite communication services(voice and Data) anywhere in the world. They called this constellation system of satellites Iridium; they crisscross the globe on a continual basis at around 17,000 miles (27,359 kilometer) per hour.

Iridium handsets are small, and are in their fourth generation design. The 9555 (last generation) is probably iridium’s best satellite handset, however they have introduced the 9575 Extreme with enhanced options- WiFi and Bluetooth capabilities for data and remote headsets.
How ever one must take note of the way the constellation works, as Iridium can have minor coverage problems, due to your location on the earth’s surface and that of the closest satellite.
Iridium is a constellation of 66 low earth orbit (LEO) communication satellites
These satellites communicate with each other directly in space, and also link up to ground stations in thirteen different spots around the world.
Iridium satellite phones can communicate through this infrastructure with any phone, anywhere, including adequate coverage of the North and South Pole.

The two satellite constellation orbits, notice how LEO (iridium) is so close to the earth and see how GEO is more than 36 times more further out in space
One of the main advantages of Iridium is that even when an iridium satellite phone is in a canyon or blocked by mountain ranges, can still obtain signal as the satellites fly overhead at different intervals and angles.
Suffice to say that it‘s the only satellite network that works at the North and South Poles. Iridium SatPhones will function with the antennas retracted, but reliability and coverage will suffer slightly.
Other factors to affect buy decisions is that iridium handsets are more costly than other providers such as inmarsat, Globalstar and tharayar; location history of the SatPhones can be tracked; panic alert buttons are present on some phones; some can even send GPS coordinates.

Looking at the Airtime Plans below, you can see that the Iridium GO 400 allows 400 data minute and 200 talk time voice minutes featuring all the usual monthly service rates and as there is monthly service agreements or contracts, in other words this prepaid option for the Iridium GO could be the best way to save money Depending on how you want to use it. However do take note that you do not get both 400 data minutes and 200 voice minutes combined to make 600 minutes, voice minutes it is billed at twice the cost of data, and vice versa the starting 400 minutes would be equal to 200 minutes of voice calling. You can use either 400 minutes of data, or 200 minutes of voice, however its not fixed as you can combine the Data and voice options and let the iridium GO prepaid card system do the math for you.
