Step 1: Confirm the count
Use the 668 service and note which operator shows more SIMs than you own. Remember old SIMs: data devices, a SIM for a parent, or one from years ago.
Step 2: Visit that operator
- Go to an official service centre or franchise of that operator.
- Bring your original CNIC.
- Ask for the list of numbers on your CNIC.
- Request blocking of every number you don't recognise. Ask for a reference or complaint number.
Step 3: Report if needed
- If the operator doesn't resolve it, file a complaint at complaint.pta.gov.pk.
- If the SIM was used for fraud or harassment, report to the FIA Cybercrime Wing.
Step 4: Recheck
After a few days, run the 668 check again to confirm the count has dropped.
Why it matters: a SIM on your CNIC is legally linked to you. Criminals use illegally registered SIMs for scams and extortion; blocking them protects you.
Frequently asked questions
How long does blocking take?
Operators usually block a reported SIM quickly, but it can take a few days to reflect in the 668 count.
Can I block a SIM by phone?
You can report it by phone, but blocking SIMs on your CNIC generally requires an in-person visit with your original CNIC.
