I do a fair bit of wilderness backpacking, and I always put my phone on airplane mode as soon as I walk into the woods, and take it off airplane mode when I get back to civilization. No Garmin InReach, but I do have a PLB for safety (here in NZ land SAR advises everybody who is in the backcountry to carry a PLB), but it has no functionality beyond "press this in case of emergency."

I once had a hiking partner on a classic hut to hut hike on the north island (Tongariro Northern Circuit, it's where they filmed mount doom and mordor) who walked out of the hut at night to find a ridge to get service to do a job interview with a company in the UK.

The disconnection from real life is a huge part of why I like to wander off into the woods, and I pray that I will never be expected to have internet in these remote places.
