SIM card was first invented and manufactured in 1991 by the smart-card maker Giesecke and Devrient in Munich. This invention revolutionized the mobile phone and tech industry. A SIM card is basically an Integrated Circuit (IC), which can securely store the international mobile subscriber identity (IMSI) number and its key, which are used to identify and authenticate subscribers on mobile devices.
In the early 2000s, as mobile phones started to gain popularity in Pakistan, these SIM cards also started to become a necessity for every household and helped people connect to their loved ones. But as the number of sim card users increased, keeping track of these users also got nearly impossible for the companies. People started acquiring unregistered sim cards for criminal activities, which made it impossible for the police to trace these criminals because there was no record against these sim cards.
To counter this, Pakistan Telecommunication Authority (PTA) introduced a new system in 2009 under which people were forced to register their sim cards with their CNICs, and now they have also introduced biometric systems around the country. Any individual, having a valid CNIC can have Five sim cards registered against their CNIC and it is very important to keep only those sim cards active that are in your personal. So, if you have any other sim cards registered under your name you should block them as soon as possible so that they cant be used in any criminal activities.
If you don’t know how you can check the number of SIMs registered against your CNIC and want to know how can you verify or even block one of them, you are at the right place.

If you are not aware of the term, SIM cloning is when someone copies all the information from your SIM card and puts it onto a different SIM card. This lets someone else use your phone number and account on a different phone, and any charges will be attributed to your original SIM card. It’s important to keep your SIM card safe and secure to prevent this from happening.
