The cheaper/lighter plbs don't give the user a gps location, they only signal that when the sos button is pressed and that signal goes to the rescuers not the user.
Garmin inreach/spot devices require a subscription paid (monthly/yearly?) inorder to be able to use the SOS function.
If the phone fails .. you will need a paper map even if some other device tells you location. Oh .. one of the inreach devices has a map capability.

Personally for navigation back up I use a paper map, I also make notes on it. For SOS I use a PLB. The phone is a nice device while it works and the battery has charge.
