@c123pk read the last paragraph again carefully , MNP main function is that if suppose u have an old number of Mobilink since 1994 and u have bought it for 4k to 5k at that time and its a golden number of its times and you say that I don't want to leave this number, its very special. it has now 12th year with me. And u r fed of Mobilink service and packages but u can't leave it because of ur number. Suppose ur golden number is 0300-5555555 u can't leave. Thats the problem many of our people have. They don't want to change or leave thier numbers.
Then MNP is there to help them, u can easily change to Telenor and u will get a Telenor SIM by giving ur Jazz SIM and from now on u will only from Telenor family and Nothing to do with the Monilink. But your Telenor SIM will have the same number 0300-5555555, i.e if i wanna call you, I will call 0300-5555555, the call will directly go to Telenor from now on.
The new connection procedure will remain the same. But if u wanna buy ufone Sim with warid code then first buy warid Sim and then through MNP convert to ufone.
