I'm wondering how did the doobie play into it. Must have been a different kind of doobie then I'm thinkingSince I did not make the arrangements I do not remember the name of the service company. I stopped using landlines many years ago so the unit I had was one that was made specifically for cells. When the alarm went off the company immediately called the number they were given. If no answer, they had a second number to call. If still no answer they called 911. I had a an alert necklace, and/or a watch-type wrist band and/or a doobie to put in my pocket. Any or all of those could detect a noise that sounded like a fall, a voice asking for help and it even had GPS so the alarm would locate me geographically so totally covered. I also don't remember the cost. I knew it was going to be used only for a short time so whatever the cost it had to be done.
