What Is SIM Information?

SIM information refers to the official registration details associated with a mobile SIM card. It includes the registered mobile network, SIM registration status, and the number of SIMs linked to your CNIC. These records are maintained by your mobile network operator in accordance with PTA regulations.

Checking the information on your SIM helps you confirm that the SIM is registered in your name and to identify any unauthorized SIMs associated with your CNIC. Verifying the information on your SIM regularly improves your security, protects your identity, and helps ensure that you are in compliance with Pakistan’s telecom laws.

How SIM Registration Works in Pakistan

SIM registration in Pakistan is done through Pakistan Telecommunication Authority (PTA). Every SIM card must be verified before activation.

Identification: your fingerprints are checked prior to issuing a new SIM.
CNIC Linkage: Every SIM on which a call is made is linked to a CNIC.
PTA Database: Registration information is stored in the official PTA database.
Mobile operators: Jazz, Zong, Ufone, Telenor, ONIC and SCO follow the same process of registration as per the PTA.
