This summer I have done more camping and hiking than ever before. Good outdoor activities for social distancing with just the wife & dog. Because we were getting into some more remote areas with spotty (at best) cell coverage I got a ham license and HT. The last couple of trips I had the area repeaters programmed in. Really only effective if you can get to high ground but...better than nothing.
You might try a Garmin InReach with sat service. It is what I use on remote backpacking trips.
