If you ever end up in the backcountry, you might want to consider a used Iridium phone. They can be found in good condition for significantly less than a flagship smartphone and check all the boxes for emergency, phone-only devices: small, rugged, makes phone calls, works very nearly anywhere without having to deal with local SIM cards or roaming, and expensive minutes provide an incentive to not use it for trivial stuff. Great for genuine emergencies and quick travel coordination, terrible for anything remotely resembling social media.
