You guys are asking about the places where there is no GSM coverage and what happens when there is jamming etc or net work congestions etc.
Well for the first one: Firstly, The GSM system covers most of the country by one network or the other. Secondly, the tendency of car snatching Hijacking and theft is more in cities than in remote areas (You can Check The stats on that) and almost allcities are pretty well covered with GSM.thirdly,car snatching is a street crime which takes place usually at the spur of the moment and very saeldom it is actually planned over days where one has to have GSM jammer with him all the time.
Now for the second one: Yes network congestions and other jaming s during VIP movements are there. But,lets be honest how many times does it happen in a day in a City like Karachi or Lahore and even if it happens everyday it certainly never happens in the whole city, and the whole day, it happens only in the area where there is VIP movement. Netwok congestions are there too for sure but how frequently????????????.
If we are so fed up with these net work congestions and all, then to hell with cell phones,lets go back to the old faithfull PTCL. Why do we all run around like mad trying to purchase newer models of cell phones at exorbitant prices when evetually they might not work becuase of network congestions.
NO! the problem is that we are all very myopic and we are just not ready to accept a change for the better we are not ready for HI-Tech instrumentation as yet. We are not looking at the BIGGER PICTURE.
