I have a pretty good GPS app on my phone, which would be more useful in that situation than cell reception (until I fall and break a leg).

Maybe I am crazy, but I'd be so depressed if I couldn't hike anymore.
I use Gaia GPS for GPS navigation, even in well traveled areas. It’s a great app.
Even places with lots of trails can get very confusing (think Almaden Quicksilver), so good nav is very useful. If you plan ahead, you download the maps for your destination area.
My wife bought me a Garmin inReach Mini Handheld GPS Satellite Communicator last Christmas which allows satellite text messaging outside cell service areas. It’s good insurance for such emergencies.
Have you ever read ‘Desert Solitaire’ by Edward Abbey? It’s about the West Southwest and it’s magnificent beauty.
