GlobalStar just introduced Sat-Fi, a hotspot device that allows up to 8 smart phones to simultaneously make calls, send SMS text message, post to social media sites, and use email via satellite. The device is two-way, allowing others back home to dial a 10 digit number to initiate calls to you while your group is out of cell phone range.

Sat-Fi is not a personal beacon device like SPOT. It requires power from a vehicle. You can use the Sat-Fi device within a range of 100 feet of the vehicle, so it's conceivable that the Sat-Fi could be in one vehicle, and passengers in a second vehicle could communicate with it. Tech specs for the Sat-Fi are here

Sat-Fi service depends on both position of satellites and local government regulations. Service also is based on the "home zone" of the customer. Today, it appears that Sat-Fi service is available primarily in the lower 48 USA states and southern Canada for customers whose "home zone" is USA. Best to check with a Globalstar dealer to fully understand what Sat-Fi and other Globalstar services like SPOT can deliver in the region you'll be traveling through. The list of dealers in USA is here

The Sat-Fi hardware costs $999, and monthly contracts to use it are expensive. The best deal for overland travel in a group would be the $150 a month plan that offers unlimited use. The basic plan costs $40 a month for 40 minutes of satellite time.
The bad news is that Globalstar requires an annual contract, rather than month to month. So signing up for the $150 a month plan is a commitment of $1800. This isn't so bad for an outfit that takes to the field on a regular basis. The Sat-Fi hardware can be moved from vehicle to vehicle easily.
