Complete step-by-step guide to checking how many mobile SIM cards are registered on your CNIC number via PTA 668 SMS service and online portals.
Why Verifying SIM Ownership Matters in 2026
Under the guidelines issued by the Pakistan Telecommunication Authority (PTA), every subscriber is legally responsible for all cellular mobile SIM cards registered under their Computerized National Identity Card (CNIC). Unused or unknown SIMs registered against your identity pose security risks, including unauthorized activity or spam.
