Since I'm gearing up for my first really big road trip, I'm very curious about a lot of the technology out there, and one thing I was wondering about are satellite devices, so I just thought I'd ask what kind of equipment people here use to help them stay in touch in places where the last hope for possible advanced communication may be via satellite.
Do you have a certain gadget you rely on for this? Do you think things like satellite phones or more affordable options like this this satellite messenger are good/worthwhile, or do you find them mostly unnecessary even when far from any means of tracking or emergency contact? What about service for these hi-tech devices? Is it expensive? Does it require a contract? Is it reliable? What do you use as alternatives? Do you take advantage of an existing GPS service on a piece of equipment you already have? And do you find that's more than sufficient?
These are the questions that come to my mind when I come across these things. Though I think I'm good for my trip being that I'm not really planning to roam far off any map, I find myself curious as to how effective and necessary these things are for those of you that have seen or might own them.
