Pakistan government is considering to stop prepaid packages of cellular networks in Pakistan. Pakistan's prepaid subscriber base is more than 80% of the whole cellular subscribers.
Reports say that these cellular network failed and are involved in wrong customers data to increase their subscribers base. Several sim cards are not registered on genuinely.
Cellular networks awards their dealers who sell their sims. Dealers use other customers Identification cards to issue new sim cards. For example in Faisalabad new mobile connection price is 50rs but if you pay 200Rs he will give you registered sim card (ie, using other customers ID card for your sim)
Networks are involved too, networks like Telenor love their customers more than government orders. In past, government asked customers to get extra connections blocked which they didn't register on their CNIC. I myself knew a number which was registered on my CNIC but not owned by me, went to Telenor customer service centre and completed the procedure to get that number blocked. But that number is still running and on my name. When contacted the company they told that they are still asking the number user to visit service centre for ownership change. It have been several months, if that number is used in some criminal activity then I will be blamed, not the number user or network.
