The cellular companies operating in Pakistan have got it wrong somewhere. One cellular company is trying to tell us in its latest advertisements that they will give us cheap rates if we talk only for '30 seconds'. There is no explanation what happens after those 30 seconds? Does the connection go dead, the phone battery tanks or the person on the other end drops dead? -SYED NAUMAN ASLAM, Wah Cantt., via e-mail, January 31.
