SIM & CNIC Self Check
This section is designed for one purpose: helping you understand and check telecom information related to yourself. It is not a private subscriber database and does not expose another person's confidential information.
How to approach your own SIM check
Use your valid identity information only for an authorized verification process.
Use the current PTA-supported method, official SIM information service or your mobile operator's authorized channel.
Check whether the SIM connections associated with your identity are familiar to you.
If a registration is unexpected, contact the relevant operator and follow its official correction or blocking procedure.
