Here is some info posted from someone in another club of mine. it may NOT be accurate.
Please correct us if it is.

* This is a start-up ... new product, very little test data available
* Relies on GlobeStar satellites ... very old equipment, mostly
obsolete, coverage maps are "optimistic" at best
* GlobeStar is near bankruptcy ... their sat phone business is falling
apart due to "poor service" issues and equipment malfunctions
* SPOT unit uses same satellite equipment ...
