I was just watching the 6pm CBC news and they were discussing a Personal GPS Alarm for 3000$CDN. There's a piece of equipment that's about 6" round and 3" thick along with a car alarm control thing. Basically if you are in trouble you push the button on the fob and it sends a message to a satelite. People can also send you a page and you've got x number of minutes to hit the reply button before it tells them you are dead (or just not around the thing, hehe). This doesn't give you the ability to talk back and forth with words but you could set up some kind of morse code system with your friends back home to send simple requests back and forth. I'm sorry but I didn't catch the name of the company marketing this product, but he lost his hand after being trapped by a machine for 3 days. During this time he came up with the idea as he could have used such a device to call for help where cell phones do not work. For this price I think a Satellite phone would be a better way of spending your money but it's fast and silent. They said oil executives in the Middle Eastern deserts carry them.
