There's lots of holes, especially with 3G (which is all holes, basically).

If we look at http://www.outfittersatellite.com/thuraya.htm or
http://www.outfittersatellite.com/iridium.htm then some of them
already have GPS built-in (if they don't, a simple Bluetooth
GPS module can be queried by a phone application), and have
solar rechargers as accessoires.

Of course, one shouldn't rely on just technology, but
have back up and fallback plans to low-technology (navigation
and ability to survive in the wild).
