75 / 100

Pakistanis were unaware of the communication device before the year 2000, which we call “mobile phone“in the present day. Now, almost every second citizen of Pakistan owns a modern and luxurious mobile phone. 

Just like everything has a disadvantage, there are some downsides to mobile phones as well. Due to the use of unregistered and fraudulent SIMs, there was a rise in terrorist attacks and various other illegal activities.

Some way steps to check SIMs on CNIC

So, to counter this issue, a sim information system became functional in 2009. PTA introduced this system to keep track of the SIMs being used by the people and the activities they do with them. Now, if anyone has to buy a SIM, they have to register it against their CNIC.

Sometimes it happens that we forget how many or which SIMs are registered on our CNIC. As you are allowed to register only a limited number of SIMs on your CNIC, it can be problematic while registering a new SIM on your CNIC if you already have registered two or three SIMs. You can register only a maximum of 5 SIMs on your CNIC. In order to register a new SIM, you have to block one of the previous registered SIMs from your CNIC. Therefore, now you must be wondering how to check SIMs on CNIC. If you want to learn the process, keep on scrolling.
