I dont know the specifics, but isnt the government able to track
you even if your handphone is switched off. You got to take out the
battery to prevent that, which is the same as throwing your phone
away.
He's a secret... the one that track you, it's the guy you keep
seeing whenever you enters a coffee shop, your teacher, your boss,
your mother, your friends, the cctv you pass by...
you are monitored by someone all the time... the government just
need to bring them down for coffee...
in addition, the government have listening posts
everywhere...
