Inmarsat GSPS
Inmarsat GSPS provides voice, SMS (texting), email-to-text and 2.4 kbps internet access. Inmarsat coverage is worldwide except for the polar caps. We recommend it for users operating between 50° N and 50° S latitude but not in mountainous terrain. A key safety feature of the IsatPhone 2 is the ability to leave a breadcrumb trail of GPS locations. For more information, please contact us.

Inmarsat GSPS Coverage:
Outfitter Satellite recommends Inmarsat GSPS service for users operating between 50° N and 50° S latitude. The Inmarsat GSPS coverage area uses three Inmarsat I-4 satellites. Unfortunately, north of 50° N or south of 50° S latitude, these Inmarsat satellites tend to be closer to the horizon so that terrain masking by local vertical obstructions such as mountains or trees becomes more of a problem. It is the responsibility of the user to consider this issue before traveling to any given location. Our customer service staff are always happy to help you determine the elevation and azimuthal angle of the satellite based on your expected location. Comparison of Inmarsat GSPS to Iridium
Inmarsat GSPS generally has lower service cost than Iridium. The current state-of-the-art Inmarsat GSPS satellite phone, the IsatPhone 2, is also priced much lower than the current flagship Iridium phone, the Iridium 9575 Extreme. Both handsets have emergency buttons. Both handsets have GPS and tracking features. The Iridium 9575 Extreme is a little lighter. A quick comparison of the most popular Iridium products to the Inmarsat IsatPhone 2 is given below.
The main advantage of Iridium is that it has global coverage that works even in mountainous regions. This is a result of the distribution of the 66 Iridium Low Earth Orbit (LEO) satellites being distributed relatively evenly around the earth. This allows Iridium satellites to look down into mountain valleys anywhere on earth. By comparison, Inmarsat uses GEO satellites that are on the equatorial plane of the earth. These satellites don't move (much) relative to the surface of the earth. As a result, Inmarsat satellites don't cover the polar regions and terrain masking is more problematic.
