I've been solo hiking, running, kayaking, and biking in areas without cell service since before cell phones were things people carried.
Haven't needed emergency search-and-rescue in 20 years, so it's just never seemed like a good investment...that's $3600 I could have 'wasted' on a service I've never needed. But I would probably buy and carry an InReach if they offered use it now, pay later plans. I don't carry a PLB, because that would mean paying for insurance, and I'd more likely need a lift from my brother in a side-by-side than a helicopter from the sheriff's office (and the ruinous costs that would entail....
I plan to wear my Fenix 6 Pro for another 10 years, but if they came out with a version with InReach 2-way texts my wife would buy it RIGHT NOW, express shipping, not even a thought of waiting for Christmas.
On the other hand, that's $3600 of profit for Apple/Garmin/Iridium/Globalstar/Spot that they're loathe to leave on the table until the one time in 20 years when I really need it.
