Skip straight to Phase 1 — Contain below and block it before reading the rest of this guide.
How To Remove An Unauthorized SIM From Your CNIC
A four-phase response plan — contain it, report it, confirm it's gone, then close the door on it happening again. Every step here is free and works directly through PTA's own systems.
Discovering a SIM registered against your CNIC that you never signed up for is unsettling, but PTA built a specific, working process for exactly this situation. Most people who follow it in order get the line fully removed within a week, without a lawyer or a court filing involved.
This guide treats the process like an incident response — four phases, each with a clear goal, so you're never wondering what to do next. Before diving in, it's worth confirming whether what you're looking at is actually a problem, since not every unfamiliar-looking entry turns out to be fraud.
Is This Actually Unauthorized?
Run through this quickly before treating anything as confirmed fraud — a few of these get mistaken for a security incident when they're really just a forgotten SIM.
Not certain which bucket applies? Run a fresh check first using our SIM owner details guide before assuming the worst — confirming exactly what's registered is always the right first move.
🛑 Phase 1 — Contain It Immediately
~1 minuteThe goal here isn't to permanently remove anything yet — it's to stop the line from being usable while you work through the rest of the process.
- Open your phone's messaging app on any working SIM with signal.
- Reply with just the 11-digit unauthorized number — no extra text — sent to 668.
- Wait for PTA's confirmation reply that the block request has been received.
📋 Phase 2 — Make It Official
~10 minutesAn SMS block is a temporary measure. The formal complaint is what actually triggers permanent removal from your CNIC and creates a record you can reference later.
- Visit cnic.sims.pk and select the option for reporting an unauthorized registration.
- Enter your CNIC, the unauthorized mobile number, and its network.
- Submit the form and save the reference number you're given — you'll need it for any follow-up.
- Prefer to talk to someone? Call 0800-55055 and a PTA representative can log the same complaint by phone.
If the SIM was used for something beyond simple registration fraud — actual financial loss, harassment, or impersonation — this is also the point to file a parallel report with the NCCIA Cybercrime Wing.
✅ Phase 3 — Confirm It's Actually Gone
24 hrs – 7 daysDon't assume the block was the end of it — the complaint needs to be processed and the SIM formally disowned before you can consider this closed.
| Stage | Typical Timeframe | What's Happening |
|---|---|---|
| SMS Block | Immediate | Line restricted while under review |
| Complaint Logged | Within 24 hours | Reference number issued |
| Verification | 24–72 hours | PTA cross-checks the registration |
| Formal Disowning | Up to 7 days | SIM permanently removed from your CNIC |
- After roughly a week, run a fresh 668 check to confirm the number no longer appears.
- If it's still listed, call 0800-55055 with your reference number to check on status.
- For a printable confirmation, visit a PTA office or franchise in person with your original CNIC and reference number.
🛡️ Phase 4 — Reduce The Odds Of A Repeat
OngoingThere's no way to make this impossible, but a handful of habits meaningfully lower the odds of it happening a second time.
- Run a 668 check every few months — it takes under a minute and catches problems early.
- Hand over a CNIC photocopy only when genuinely necessary, and keep track of where each copy ends up.
- Report a lost or stolen CNIC to NADRA immediately — this is one of the most common paths to unauthorized registration.
- Walk away from any franchise that offers to skip biometric fingerprint verification — a legitimate registration always requires it.
