How Many SIMs Can You Register on CNIC?

A common voice search query is, “How many SIMs can I register on my CNIC?” PTA rules are clear. Each person can register a maximum of five SIMs per CNIC across all networks.

This rule prevents misuse. If you already have five SIMs and want a new one, you must first block or cancel one of your existing SIMs.

Checking your SIM count is important. Many people forget old SIMs they no longer use. Some of these may still be active. Fraudsters can misuse them. By checking your SIMs, you can block the old ones and stay safe.

If you ever wonder, “How do I check how many SIMs are on my CNIC?” use the PTA portal or SMS code. Both show the total SIM count in seconds.

What is SIM Cloning and Why Is It Dangerous?

SIM cloning is when someone copies your SIM card onto another one. This cloned SIM can receive your calls, texts, and even one-time passwords (OTPs). Criminals use cloned SIM cards for scams and other illicit activities.

SIM Cloning Risks:

• Loss of Control: A cloned SIM can give criminals access to your phone calls and texts.
• Fraud: Criminals can use your number to trick people into giving them money or personal information.

How to Spot SIM Cloning:

• No Network: You may lose your signal or experience a network connection issue.
• Calls You Didn’t Make: If people get calls from your number that you didn’t make, your SIM might be cloned.
• Quickly Vanishing Balance: If your balance disappears fast, that’s a red flag.

Real-Life Example: There have been cases where criminals used cloned SIMs to steal money or commit fraud. These incidents demonstrate the serious dangers of SIM cloning.

How to Prevent SIM Cloning:

• Enable Two-Factor Authentication (2FA) on your accounts for extra security.
• Monitor your SIM Usage regularly.
• Contact Your Operator right away if you notice anything unusual.

If you suspect that your SIM has been cloned, visit your operator’s office and report the issue immediately. They’ll help block the cloned SIM and protect your account.

How to Block Unwanted SIMs Linked to Your CNIC

Want to block unused or unknown SIMs linked to your CNIC? It’s easy to stop fraud and protect yourself.

Here’s a simple, step-by-step guide:

1. Visit the nearest customer service centre
   Go to the service centre or franchise of your SIM provider (e.g., Jazz, Zong, Telenor, Ufone).
2. Bring your original CNIC
   You’ll need to present your CNIC to verify your identity.
3. Ask them to block the SIM.
   Let them know you want to block any unused or unknown SIMs linked to your CNIC.
4. Please fill out the request form and sign it
   Complete the form provided by the customer service representative.
5. Done!
   Once blocked, the SIM will no longer count toward your 5-SIM limit.

Customer Service Numbers:

• Jazz: 111
• Zong: 310
• Telenor: 111-345-100
• Ufone: 333

By blocking unused SIMs, you stop fraud and regain control over your CNIC.

Understanding the Biometric Verification System (BVS) for SIMs

The PTA introduced the Biometric Verification System (BVS) to prevent fraud and unauthorised SIM use. Now, your biometric fingerprint is required for SIM verification for many SIM-related tasks.

Here’s how it works:

• Get a new SIM: Your fingerprint verifies your identity when you buy a new SIM.
• Transfer ownership: To transfer a SIM, you must verify it with your fingerprint.
• Re-verify existing SIMs: You’ll need to re-verify your SIM periodically using your fingerprint.
• Replace lost or stolen SIMs: If your SIM is lost or stolen, you will need to undergo biometric verification to obtain a replacement.
• Port numbers between networks: If you want to move your number to a new network, you’ll use biometric verification.

Why is it important? Biometric verification helps prevent fraud and ensures that only the rightful owner can activate, transfer, or use a SIM. Without BVS, your SIM won’t stay active for long.

How to Get Biometric Verification for Your SIM

Want to verify your SIM biometrically? Follow this:

1. Go to the nearest service centre of your SIM provider.
2. Take your CNIC and the SIM card.
3. Place your thumb on the biometric scanner.
4. Once verified, they’ll confirm your ownership.

This process is fast and ensures your SIM won’t get blocked due to an unverified status.

What Happens If You Use an Unregistered SIM?

Using an unregistered SIM card is a criminal offence and can result in severe legal consequences. Penalties for using unregistered SIMs include:

• Fines: You may face substantial penalties for using a SIM card that is not registered in your name.
• Arrest: Using unregistered SIMs may lead to arrest, depending on the circumstances.
• Criminal Investigations: Unregistered SIMs are often linked to criminal activities, and you could be involved in investigations.

SIM registration laws are strict, and failure to comply can result in significant problems.

Avoid this at all costs. If your SIM is not registered under your name, update it or have it blocked immediately.

1. Visit your network provider’s franchise: Go to your SIM provider’s nearest customer service centre (e.g., Jazz, Zong, Telenor, Ufone).
2. Bring the CNICs of both the old and new owners: Both the original and new owners must be present with their CNICs.
3. Fill out the ownership change form: Complete the necessary paperwork provided by the customer service representative.
