I got the idea because my mom (89yo) is pretty tech-savvy for her age and has no problem using her cellphone but she had a couple of incidents where she fell and the phone was out of reach as nobody normally carries it around the house (well I know a few exceptions to that) so the device could act as a wearable speed dial button of some sort. There are some devices like that but I believe they use their own network and subscriptions. EDIT:Found one https://silentbeacon.com/product/panic-button-safety-beacon/ https://silentbeacon.com/product/panic-button-safety-beacon/ I might purchase one to test. About $59 USD sounds reasonable.
