غیرمجاز سموں کے خطرات:

اگر آپ کے CNIC پر کوئی نامعلوم سم رجسٹرڈ ہو اور اس سے کوئی جرم ہو تو پولیس سب سے پہلے آپ سے پوچھ گچھ کرے گی۔ مالی دھوکہ دہی، شناخت کی چوری، اور سیکیورٹی خطرات بھی ہو سکتے ہیں۔

How Unauthorized SIMs Get Registered on Your CNIC

Common Ways This Happens:

1. CNIC Lost or Stolen

• Your CNIC lost and someone found it
• Used for SIM registration before you reported it
• Multiple SIMs registered quickly

2. CNIC Photocopy Misused

• You gave photocopy for legitimate purpose (job, rental)
• Photocopy used without permission for SIM registration
• Common with domestic workers, tenants

3. Corrupt Retailer/Franchise

• Some retailers register SIMs on random CNICs
• Sell to customers without proper verification
• Make money without following rules

4. Family Member Registration

• Family member registered SIM without telling you
• Used your CNIC “temporarily”
• Forgot to inform you

5. Identity Theft Ring

• Organized criminals steal/buy CNIC data
• Register multiple SIMs for fraud
• Sell to others for illegal use

6. Old Forgotten SIMs

• You registered SIM years ago and forgot
• Never used it but still active in system
• Not technically “unauthorized” but unknown to you

Step 1: Confirm Unauthorized SIMs on Your CNIC

Before Blocking, Verify First:

Action A: Check via 668

1. Send your 13-digit CNIC (without dashes) to 668
2. Note the total SIM count
3. Note operator-wise breakdown
4. Compare with SIMs you know about

Example Result:

Total SIMs: 5
Jazz: 2
Telenor: 1
Zong: 2
Ufone: 0

Analysis:

• If you only use 2 SIMs (1 Jazz, 1 Telenor), then the 2 Zong SIMs are unauthorized
• You need to investigate Jazz (2 SIMs when you think you have 1)

Action B: Identify the Specific Operators

• Based on 668 results, note which operators have discrepancies
• Example: If 668 shows 2 Zong SIMs but you never used Zong = clearly unauthorized

Action C: Recall Possible Explanations

• Old SIM you forgot about?
• Family member used your CNIC?
• Job application where you gave CNIC copy?
• Rental agreement where landlord kept copy?

If you cannot explain the extra SIMs = They are UNAUTHORIZED and must be blocked immediately!

تصدیق کریں:

بلاک کرنے سے پہلے، 668 سے چیک کریں کہ واقعی نامعلوم سمیں ہیں۔ پھر سوچیں کہ کیا یہ آپ کی پرانی سمیں ہو سکتی ہیں یا کسی فیملی ممبر نے استعمال کی ہوں۔

Step 2: Visit Operator Franchise to Get Actual Phone Numbers

Why This Step is Critical:

668 only shows the COUNT of SIMs, not the actual phone numbers. You need to know the exact numbers before blocking.

How to Get Phone Numbers:

Step 1: Prepare Documents

• Original CNIC (must not be expired)
• Photocopy of CNIC (helpful but not mandatory)
• Notebook and pen to write down numbers
• Your own phone for reference

Step 2: Visit Correct Operator

• Based on 668 results, visit the operator with unauthorized SIMs
• Example: If 668 shows 2 unauthorized Zong SIMs, visit Zong franchise

Step 3: Go to Official Franchise

• Don’t go to small retailers
• Visit official franchise/customer care center
• Look for proper signage and professional setup

Operator Franchise Types:

• Jazz: Jazz Business Center, Jazz Service Center
• Telenor: Telenor Service Center, Telenor Customer Care
• Zong: Zong Customer Care Center, Zong Service Center
• Ufone: Ufone Customer Service, Ufone Franchise

Step 4: Request SIM List

• Approach customer service counter
• Say: “I need to see all mobile numbers registered on my CNIC”
• Show your original CNIC
• They will check their system

Step 5: Write Down All Numbers

• They’ll show you complete list of phone numbers
• Write down EVERY number
• Note registration dates if shown
• Note active/inactive status

Step 6: Identify Unknown Numbers

• Check each number against your records
• Call/SMS unknown numbers to see if they’re active
• Ask family members if they recognize any
• Mark clearly which ones you DON’T recognize

Example List:

✅ 0300-1234567 - Your main number
❌ 0300-9876543 - Unknown (registered 2023)
❌ 0300-5555555 - Unknown (registered 2024)

Step 7: Request Blocking

• Point to the unauthorized numbers
• Say: “I want to block these numbers immediately”
• Fill out blocking request form

فرنچائز پر جانا:

اصل شناختی کارڈ لے کر متعلقہ کمپنی کی فرنچائز جائیں، تمام نمبرز کی لسٹ مانگیں، نامعلوم نمبرز کی نشاندہی کریں، اور فوری بلاکنگ کی درخواست دیں۔

Frequently Asked Questions

Q1: How long does it take to block an unauthorized SIM?

A: If the operator cooperates, blocking happens within 24-48 hours. The 668 system updates within 48-72 hours. If they refuse, involving PTA can take 7-15 days.

Q2: Do I need a police report to block an unauthorized SIM?

A: Not usually. For 1-2 unauthorized SIMs, your CNIC and identification at the franchise are sufficient. Police reports are helpful for multiple SIMs or suspected identity theft rings.

Q3: Can the operator refuse to block a SIM registered on my CNIC?

A: Legally, NO. If a SIM is registered on your CNIC without your authorization, you have the absolute right to block it. If they refuse, immediately file a PTA complaint.

Q4: What if the unauthorized SIM has an outstanding bill?

A: You are NOT responsible for bills on SIMs you didn’t use. The operator cannot demand payment. If they insist, file a complaint with PTA about this illegal practice.

Q5: Will blocking affect my other SIMs?

A: No, blocking only affects the specific numbers you request. Your legitimate SIMs continue working normally.

Q6: Can someone re-register a SIM on my CNIC after I block it?

A: Not easily. After blocking, the operator should flag your CNIC for that number. Future registrations require biometric verification. However, keep checking 668 regularly.

Q7: What if I block a SIM by mistake?

A: Contact the operator immediately. If blocked recently (within days), it might be reversible. Otherwise, you may need to register a new SIM.

Q8: Do I have to visit every operator separately?

A: Yes. Each operator (Jazz, Telenor, Zong, Ufone) has separate systems. You must visit each one that has unauthorized SIMs.

Q9: Can I block SIMs online without visiting franchise?

A: Not directly. Most operators require in-person verification for security reasons. However, PTA complaints can be filed online, and they’ll direct operators to block.

Q10: What legal action can I take against the person who registered SIMs on my CNIC?

A: You can file a police report for identity theft under PECA (Prevention of Electronic Crimes Act) 2016, which carries penalties up to 3 years imprisonment and heavy fines.
