Taleban issue mobile phone threat

The Taleban has ordered mobile phone carriers in Afghanistan to "turn off" its signals at night so that foreign troops can not track their movement or else they will blow them up (the towers that is). But before they waste any TNT couldn't they just turn their cell phones off at night and avoid the infidels tracking their nocturnal movements? And besides...... if they blow up the infidels' towers then it will disrupt their mobile coverage all together. Doesn't sound like the T'ban is thinking this one through. 

I digress here but it sounds like it must be easier to get a mobile phone plan in Afganistan than it is in the US or Europe because something tells me that if i called Tmobile about getting a plan and gave  "cave" and "jihadi" as my address and occupation, respectively, then they'd probably give me a hard time getting a plan.
