Two options you might consider are:<br>1) Amateur radio<br>2) Satellite phone<br><br>Amateur radio licenses are easy to get these days, and you can have decent range (50mi+) on the popular 2m band if you can hit a repeater. Other bands can reach around the globe, but require larger equipment not well suited for portable / survival use.<br><br>A satellite phone is also an option, provided you have a clear view to the sky. The Iridium network (www.iridium.com) is apparently back in business, with global coverage. <br>INMARSAT phones might work as well, but I don't know much about those. Any internet search could help you there<br><br>Obviously, these won't necessarily cut down the response time by much, but they may be able to put you in contact with medical personnel who can direct any potential treatment while help arrives. <br><br>Good Luck<br>-Matt<br><br>
