Don't rely on the mobile phone, it is a convience and can be a life
saver *IF* you have coverage *AND* the battery isn't flat. It could
remove the 5 mile walk to the nearest civilasation to summon help
but you must be able to stay put and survive or navigate your own way
off without it.

A GPS can be useful but mainly as a compass and something to give you
your position on the map. Very handy in fog/snow/night when you can't
see any landmarks. But again only an assistant.
