As I noted in my original post the motive here was to be able to use a SATELLITE network to send a text to an ERS. I also think it would be beneficial to be able to do so via CELLULAR as well (as MrWizard noted), and also with an app (and remember an app might use different ways to communicate; as far as I can tell all the AAA/GS ones use data right now).
From what I can tell with DeLorme's device, eg, it can send a preprogrammed text with GPS at the touch of a button to their rescue service (life and limb type rescue, not ERS). And it can communicate with USBoat for boat tows via sat/text. Two way. And with local emergency services (unclear to me if this is like a text to 911, or relayed through their rescue provider).
All I need is an ERS provider that has a cellphone next to their dispatcher so I can text that to get help for a breakdown. Geez, I never thought it wouldn't exist. You can request help via various apps on a smartphone, but they only work in cellular or wifi range.
A voice sat phone would work, of course, but I like the idea of a relatively inexpensive device like the Explorer, which can also RECEIVE an emergency text via satellite FROM someone at home, like "plz return. Home buring down."
