I own a Garmin InReach that I regularly take with me on hiking expeditions (mostly Scotland, Iceland and South Africa) and it’s super handy on remote areas with no coverage. The ability to send an SOS is the main feature, but the two-way messaging system is just amazing for peace of mind, for me and my family. However, the main thing about the InReach is its ruggedness and battery life, which I consider essential. I always carry an iPhone with me that I use when and if I get reception, but I need to carry a battery pack for it and it’s always in the back of my mind that an iPhone is a relatively fragile device and it’s one misstep away from cracking/breaking/etc, hence the inReach.

Moving forward, having both will be great, but I think having to rely only on an iPhone would make me a bit nervous, so I’m not sure how much of a threat this is for the inReach devices (at least for now).

I think this drastically underestimates or at least undersells the impact of convenience, or in this case the maximum possible level of convenience which is already having the feature even if you don't know it. Similar arguments could have and indeed were made for every other small electronic device the smartphone has replaced. It's not that the advantages you listed don't exist, it's just that they won't hold a candle to the explosion of smartphones with satellite messaging built in by default. I feel like even just 1 year (and 200 million satellite-enabled iPhones) from today pointing out these advantages is going to look like people pointing out that land lines have better audio quality and lower latency than cell phones.

I always carry my InReach with periodic location sharing enabled when I'm on backpacking trips. I also almost always carry it during international travel and road trips, but not usually with periodic location sharing. If iPhones start offering plans with periodic location sharing, I'm fairly confident that I'd stop carrying the InReach unless I was on a particularly remote trip that was outside of my comfort zone (which isn't something I really do anyway).

I may be taking trips you’d be uncomfortable with, but the InReach is invaluable for two-way messaging and weather updates. I haven’t needed the emergency service (knock on wood), but I’ve used most of the other things it does. My phone is a much better GPS, though, and if Apple makes it possible to do those two things I mentioned at first without it using much of the battery life I’d consider only keeping my InReach for extended trips.

There’s something to be said for convenience that worries me a bit with this. The amount of people that may be “misusing” this feature and the strain that it’s going to put on,say, mountain rescue. If people start feeling more confident than their capabilities, or they ignore weather reports just because they can be rescued with an iPhone, I don’t know what effect that’ll have on these resources.

I’m thinking of backcountry hunting applications personally. When I’ve been completely away from cellular service and put my phone on airplane mode and low brightness it goes for several days without a charge as a (not always on) gps and camera. Since these trips have usually been in groups of 3-4 the fragility of the phone is a smaller issue.

But I get what you’re saying, if you have 2 you have 1 and if you have 1 you have none. Some redundancy so nice and the iPhone as a backup to the inreach will be a likely set up.
