> you won't die if you break a leg I'm sure you're already aware, but you can outright buy (ie no ongoing cost although they're deliberately expendable) devices which solve just this narrow problem (the upkeep cost is paid by various governments) via COSPAS SARSAT. Now, in practice for a lot of people "My wife/boyfriend/mother/son worries when I'm out here" is a bigger problem than "There's a tiny risk I need rescuing" but I think it's reasonable that this peace of mind costs money at least in a world where we still unaccountably don't treat public WiFi as a normal thing society should have† The no-ongoing cost technology is a Personal Locator Beacon and is electronically almost identical to its sisters on boats, an EPIRB, or on planes, an ELT. † One of the the nice things about working for a University again is EduROAM, which means WiFi just works for me in lots of places because there's a university, or a college affiliated with a university or some other situation where academics were like "Why doesn't this just have WiFi like on campus?" and EduROAM means your home institution vouches for you but you can use the network anywhere on the planet.
