This is for one of those "I've fallen and can't get up" devices for seniors to call for help.
I don't know what their model has but I bet it has a monthly fee to keep it working.
If you're going to pay a monthly fee for one, then be sure it works off cell phone towers,
so the button will work even if you're away from home, out of range of your home phone.
I just got a voicemail about senior help blah blah blah to my Burner number. How the hell did they get that number? Automated voice with a "Press 5 now to be removed from our senior citizen advisory list." Of course it was in a voicemail so that's not possible...
