Overview of CNIC SIM Verification
Under the direction of the Pakistan Telecommunication Authority (PTA), all telecom operators in Pakistan—including Jazz, Zong, Telenor, Ufone, and Warid—maintain a central database linked with NADRA. This system guarantees that no mobile SIM card can be activated without biometric fingerprint authentication.
