I agree that unless you are running an HF rig, chances of contacting someone for help in remote areas can be pretty limited. Still, the wilderness protocall is in place for just such a reason. There are not a lot of folks doing this, but I have made contact before. Here's some info: https://harriscountyares.org/training/EME/EME-112.pdf
In addition, another option in an emergency is to carry a PLB (personal locator beacon) These work the same way as the 406mhz EPIRB's used on boats and ships. They are very limited unlike the Inreach and other sat products, in that they only transmit an emergency notification to a satellite, with no two way communication,or a description of your problem, only a message to rescue centers that someone has pushed the panic button. They do send your GPS position though. The real big upside to these is that there inexpensive and there is no monthly or yearly fee. You simply register the unit to your address, and include a couple emergency contacts so that the rescue coordination center can contact them for further information in helping to determine the nature of you emergency, or to help determine if your 3 year old accidentally pushed the button.

Finally, a 2m radio will be far superior to most other forms of communication when out on the trail, I find when out in the woods, I can routinely reach out several miles while radios like CB and FRS are mostly line of sight.
