I'm not sure your concept of "remote areas" matches my reality. I was pretty happy with my Moto 4G phone at my residence in 2020, using TMO 4G. I bought an iPhone 12 mini in January 2021, that used 5G. I fell back to using mostly 4G for the first several months, it had better service. Then TMO re-tuned their antennas for 5G (I assume), my house then had crappy 4G and 5G service. Like it would only work upstairs, near a 4G booster. Or maybe place a call outdoors, then it would drop after a minute or two. This is in in the greater Lansing area, 540,000 people in the MSA, 4 county area.
Since the phone supports two lines, I switched to using Ting (TMO service still) for ~$15 month (data extra), and Visible (Verizon service) for $25/month, unlimited everything. So now I have dual service, still finding lots of areas with no service. There is a nice state park north of Lansing, Sleepy Hollow. Lots of areas there with no TMO or VZW service. Not exactly remote, probably not dangerous, I could hike to a high spot in ten minutes, maybe.
Then I started spending more time in Northern Michigan. North Country Trail in Emmet county near Wilderness State Park- very limited service. Now I'm living part time in Antrim county, paying for the two lines still, generally have crappy service in the rural areas. Turns out maybe AT&T has better service here, going to drop the Ting/TMO and switch to that. But also Apple has come out with satellite service for two years free, on all their iPhone 14 and 15 models. Hoping to switch to a 15 next year. Hopefully I can drop one line and pay $25 per month for phone service.
I've been watching the satellite communicators for several years. The Moto one seems like a good solution, might get one as a backup. I doubt Apple pays more than $5 in the phone for satellite support? Not sure how much they are paying the satellite company, but didn't they buy 50% interest in it? They must think it is a good feature.
Hopefully the TMO + Starlink service will work too. I imagine in a few years it might serve as emergency backup, and only people that need it will be able to pay $20 for an emergency 911 type satellite call.
Finally, I just want to say the cell companies service maps are crap. Drastically over estimate service areas. If the map says "fair", it is crap. If it says "good", maybe fair, one bar in some spots. I had high hopes a few years back for TMO 700MHz service, hasn't really panned out.
