Place your phone next to a radio or similar device that picks up
interference when your mobile transmits. You will soon see that with
the phone switched off it is sending and receiving no data whatsoever,
so there is no chance of anyone tracking you if the phone is switched
off.
Simple triangulation will give a very accurate position of the user
when the phone is switched on, and if its on and you aren't using it
it still transmits data back to the network now and again, so they
could still track you.
