Where in the wild world you plan on going that you think you'd need a sat phone? Leaving the country? If you aren't even leaving Utah, that's wasted cash. Unless your legs are just painted on and don't actually work, you'll never get out of fairly easy walking distance of a cell signal around here. It's depressing... One of the reasons it's depressing, is it has brought more people out, the ones that don't feel safe unless they can call someone. It's fear based, and not connected to reality, and they really shouldn't be there at all if they don't feel safe without a phone, the phone ain't going to fold space and time for them, they'll still need to handle their own crap if it becomes necessary. But chances are really, really good, it won't be necessary.
Talk about removing all traces of adventure spice though. But just go out and see if your phone works. Sadly, it probably will...
A sat phone is overkill for 99% of situations but if it isn't a large expense for your budget it isn't a bad idea to have yourself covered for that 1%. If you are out there by yourself things can definitely go wrong in very bad ways. What about a breakdown and an injury that makes it so you can't walk to get help or a cell signal? The probability of that happening isn't high but if it did happen it sure would be worth having spent that money.It's none of my business. I just think if you actually got out and did some camping first, you'd probably realize a sat phone just to go camping is just plain silly.
