To address this critical issue, the Pakistan Telecommunication Authority (PTA) took a proactive step in 2009 by establishing the SIM Information System (SIS). This online platform serves as a central repository for all SIM card registrations, allowing users to: Check the number of active SIMs registered under their CNIC.

What is SIM Cloning?

SIM cloning involves copying a SIM card’s identifying information onto another SIM card. This allows the copied SIM card to function as the original, granting unauthorized access to calls, texts, data usage, and potentially compromising your account and personal information.

Why Be Aware?

SIM cloning poses a significant security risk, enabling attackers to:

  • Steal your personal information: Access personal details stored on your SIM card, such as contacts, call logs, and messages.
  • Incur fraudulent charges: Make unauthorized calls, send texts, and use data at your expense.
  • Track your location: Monitor your movements through your phone’s location services.
  • Impersonate you: Receive calls and messages intended for you, potentially posing as you to others.

By understanding the risks of SIM cloning and adopting these preventive measures, you can significantly empower yourself to protect your privacy and prevent financial losses. Remember, staying vigilant and taking proactive steps are crucial in safeguarding your information and maintaining secure mobile communication.

Will removing SIM cards stop tracking?

Removing the SIM card will partially stop your device from being tracked. While it will prevent location tracking through mobile networks, your device can still be tracked if:

  • Wi-Fi is enabled: Your device can be tracked through connected Wi-Fi networks using a process known as Wi-Fi triangulation.
  • GPS is enabled: Even without a SIM card, your device’s GPS can be used to pinpoint its location.
  • Find My Device is active: Some built-in features like “Find My Device” on iPhones or “Find My Device” on Android can be used to locate the device remotely even if the SIM card is removed.

How do I find my SIM number?

There are three ways to find your SIM number:

  • Dial a specific code:
    • Android: Dial *#06# and your SIM number will be displayed on the screen.
    • iPhone: Go to Settings > General > About > IMEI. The last 15 digits of the IMEI number are your SIM card number.
  • Check your phone’s physical SIM card: Most SIM cards have the number printed directly on them.
  • Access SIM card information through your phone:
    • Android: Go to Settings > About Phone > Status > SIM Card Status > SIM Card Number (ICCID).
    • iPhone: Go to Settings > General > About > IMEI/MEID. The last 15 digits of the MEID number are your SIM card number.

How many SIMs can be registered against one CNIC?

As per PTA regulations, an individual can have a maximum of 5 SIM cards registered under their CNIC at a time. However, some mobile operators may have their own restrictions, so it’s always best to check with your provider for the latest information.
