What is CNIC and Why is it Important for SIMs?
A CNIC (Computerized National Identity Card) is your ID card in Pakistan. It’s issued by NADRA and is needed for many things—like getting a job, opening a bank account, or buying a SIM.
When someone buys a new SIM, their CNIC is used to register it. This helps stop illegal use of mobile numbers. But sometimes, a SIM gets registered with your CNIC without you even knowing! That’s why you should check your SIM numbers online regularly.
