How to Check SIMs on Your CNIC: Easy 668 SMS and Online Method
Check how many SIMs are registered on your CNIC by SMS to 668 or online, the 5 voice + 3 data SIM limit, and how to remove a SIM that is not yours.
Quick answer: To check SIMs on your CNIC and see how many are registered, send your 13-digit CNIC number (without dashes) by SMS to 668, or enter it on the SIM Information System portal at cnic.sims.pk. Under PTA rules, one CNIC can hold at most 5 voice SIMs and 3 data SIMs for personal use.
Checking matters: PTA has warned that any misuse of a SIM is the sole responsibility of the person it is registered to. If you find a SIM you never bought, get it removed straight away.

Found a SIM You Don’t Recognise? Do This
- Note which company issued it from the 668 reply.
- Visit that company’s franchise or customer service centre with your original CNIC. Ask them to show the numbers on your CNIC and block or remove the one that isn’t yours. Biometric verification is usually required.
- Keep the complaint or ticket number as proof.
- If the SIM was used for fraud, report it to the NCCIA. See how to report cybercrime.
Read PTA’s current rules on deactivation in PTA SIM blocking rules 2026. If your CNIC itself is lost, start with NADRA lost CNIC replacement so no one can misuse it to get SIMs.
Good Habits to Protect Your CNIC
- Check your SIM count every few months, and always after losing your CNIC or phone.
- Never give your thumbprint to street vendors for “free gifts” or “prize” offers. Thumbprints are used to issue SIMs.
- When you stop using a SIM, close it at the franchise instead of just throwing it away. Unused numbers can be recycled to new users, which can affect linked accounts like WhatsApp. See PTA and Meta blocking WhatsApp accounts on recycled SIMs.
FAQs
Does 668 tell me the actual phone numbers?
No. It gives the count of SIMs per mobile company. For the numbers themselves, visit the operator’s franchise with your original CNIC.
Can I check SIMs on someone else’s CNIC?
The system accepts any CNIC number, but only check your own or a family member’s with their permission. Removing a SIM requires the CNIC holder’s own biometric verification.
What happens if I have more than the allowed SIMs?
Extra connections can be blocked under PTA rules. Close SIMs you don’t use to stay within 5 voice and 3 data SIMs.
