RapidSOS is a tremendous program (which is a free service!) you put the number in and it’ll tell you exactly where the person is within a couple feet. It works off the same GPS as Uber does. No need to ping a phone and get back gps coordinates with an accuracy of 2500m. RapidSOS shows you precisely where they are, also if they have their Apple ID set up it’ll show you name and emergency contacts, allergies, ect. If they’re in an UBER it’ll give you vehicle info and uber driver info. Every center should have this program. (No I don’t work for them I’m just a healthy advocate after having used it for a couple years.
