Iridium is the only true global satellite network. It is the only choice for any adventurer going to the Arctic Ocean or Antarctica, as well as for Ocean crossings.
Iridium's data speed is slower than Globalstar and Thuraya, but it's the only way to go if you travel all over the world and want only one Sat phone. Voice quality is surprisingly good, with only a short delay. Iridium is the top choice for ocean rowers, world circumnavigators and polar expeditions.
Iridium is frequently used with a PDA or laptop and CONTACT 3.0 software to transmit pics and dispatches. Images work well, but video clips must be kept very short (3-6 sec).
Coverage Area - Global
