I've asked before, but I'm ever hopeful: is there an emergency roadside service or dispatcher that can be contacted via text message? And would be willing to dispatch?
The Inreach can do an SOS to their contractor, but that's life or death stuff. Not a mechanical breakdown or various other non life or limb threatening emergencies. At least with ERS I know I could get vehicle towing and help, along with 911 stuff. Still not sure about just evacuation (which can be different than a medical emergency). Last time I checked it was still pretty much voice only. And most land agencies and 911 centers are voice only. So that kinda limits the utility of the Inreach IMHO.
Globalstar and I think some other sat phones are getting as low in price as $500, although the plans are still too pricey. So I'm still on the fence.
