I just purchased a Garmin Inreach-mini.  I hike and ski alone in the backcounty, I know the terrain I hike and ski.  What I wanted is a device that has an SOS, in case something unforeseen happens (fires, phsycial emergencies, etc).  I found out that the SOS function on the Garmin device requires a subscription, is there a device that is solely used for emergency notification?
