In Pakistan, every SIM card must be registered against a valid Computerized National Identity Card (CNIC). This system is designed to ensure transparency and security in telecommunications. However, a growing problem has emerged — unauthorized or illegal SIMs being registered under people’s CNICs without their knowledge.

Many individuals only discover this issue when they receive suspicious messages, unknown calls, or face unexpected legal complications. If left unchecked, these illegal SIMs can expose you to fraud, identity theft, and even criminal investigations.
