All Iridium products operate anywhere on the planet, which means both North and South poles, open oceans, all continents, stationary or moving or flying as long as the GO is exposed to the open sky. And with a 100 foot (30 meters) Wi-Fi range, one may connect a smart device to the GO while inside.

There are 66 Iridium satellites in various Low-Earth-Orbits, 490 miles above the Earth’s surface, traveling from horizon to horizon with a maximum view time of 10 minutes each. Here is a Youtube Video that shows the Iridium orbits. When one satellite drops below the horizon, another is already in view… however for best results to stay connected, use the GO! under a big sky.

Iridium GO! – Data Minutes

Iridium GO! data minutes are simply a dial-up connection to the internet. When browsing or using email, your GO! terminal will automatically connect to the Internet by dialing a phone number. Since it is a phone call to the internet, it’s billed on a per-minute basis.

Also, since the GO! can only make one call at a time, you can’t be on the internet and make a phone call at the same time. For new subscribers, we highly recommend using the unlimited data plan when initially starting GO! service since you can be connected any length of time. Once acclimated to the GO!, downgrade to a lower plan if you find that you are not using the service much.

Iridium GO! GPS Tracking

The Iridium GO! has a valuable GPS tracking features that can instantly show your current GPS to any email or SMS text of your current location instantly. Emails or SMS texts also include a web Google Maps link to your current location.

Iridium GO GPS tracking can also be automated where the GO’s GPS location is sent every 5 minutes to once a week… an excellent option for fleet tracking or mapping of maritime vessels. Iridium GO Tracking Information.
