Exactly.

Radio technology is extremely mature nowadays, especially
with software radios and global coveragey satellites. A mobile phone (with
some foldable photovoltaics or a crank dynamo) could easily
double as an emergency beakon.

With a satellite phone with integrated GPS getting help is a no-brainer.

Notice that vehicle tracking (by GRPS) can now be done for 
40 EUR/month with a proprietary GPSoverIP protocol, with 
300-400 EUR worth of hardware.
