CEric G: There is NO cellular reception in the areas where Marv was or where they lost their way. NO texts would get out, and it would further drain the cellular device's battery searching for service.
People are lucky to get a connection at t he summit. The only units that can report locations where they were are either SPOT or InReach units.
I have a Garmin gps unit, and I can assure you, figuring out where you are on those tiny maps with a tiny triangle visible makes it really hard to figure out where you are. We don't even know if their gps units even had a decent map loaded.
