"In 2025, your SIM security is three taps away—no more identity theft, no more ghost connections."

Part 1: Check SIMs Registered Under Your CNIC

  1. Compose SMS: Type your 13-digit CNIC (without dashes, e.g., 4220112345678).
  2. Send to 668: Cost: ₨ 2 + tax.
  3. Receive Details: Reply lists all active SIMs, operators, and registration dates.

Method 2: PTA Website (Detailed Report)

  1. Visit cnic.sims.pk.
  2. Enter CNIC + solve CAPTCHA.
  3. View table showing:
    • Mobile numbers linked to your CNIC
    • Network operators (Jazz/Zong/Ufone/Telenor)
    • Biometric verification status
    • Registration status (active/inactive).

Method 3: MyPTA App

  1. Download MyPTA (Google Play/App Store).
  2. Register with CNIC + mobile number.
  3. Access real-time SIM details.

Part 2: Block Unauthorized or Lost SIMs

Step 1: Block via Mobile Operator

  1. Visit Franchise: Carry original CNIC + copies to operator’s outlet (Jazz/Telenor/Zong/Ufone).

  3. Helpline Support:

| Operator | Helpline | | :--- | :--- | | Jazz | 111/321 | | Zong | 310 | | Ufone | 333 | | Telenor | 345 |

Step 2: Report to PTA (If Operator Fails)

Part 3: Block Stolen/Lost Phones via DIRBS

Method 1: PTA DIRBS Portal

  1. Visit dirbs.pta.gov.pk → "Block Lost/Stolen Device".
  2. Enter device IMEI (dial *#06# to find IMEI).

Method 2: PTA CMS App

  1. Install PTA CMS (Device Blocking App).
  2. Log in → Enter IMEI + police report copy.
  3. Track blocking status via SMS alerts.

Note: Blocked phones cannot be used on any Pakistani network.

  • SIM Limit: Max 5 SIMs/CNIC.
  • Deceased User Cleanup: 163,200+ illegal SIMs blocked since June 2025.

Troubleshooting & Pro Tips
