How to Change SIM Ownership and Block a Lost SIM in Pakistan (2025 Guide)

Losing access to your SIM card or needing to transfer it to another person is more common than you think. In Pakistan, SIM cards are directly tied to your CNIC (Computerized National Identity Card), and leaving one registered under the wrong person can lead to serious security risks. Whether you want to transfer SIM ownership to a family member or need to block a lost SIM, this guide explains the step-by-step process for Jazz, Zong, Telenor, and Ufone in 2025.

Why Change SIM Ownership?

Changing SIM ownership is not just about convenience — it’s a security necessity. Here’s why:

• Protects you from legal issues if your SIM is misused.
• Ensures all SMS, OTPs, and bank verifications go to the rightful owner.
• Prevents SIM fraud, scams, and identity misuse.
• Aligns with PTA (Pakistan Telecommunication Authority) regulations, which require correct SIM-to-CNIC registration.

Note: While you can inquire online about SIM ownership, the actual transfer requires visiting a franchise or customer service center for biometric verification.

Benefits of Changing SIM Ownership

• Avoids fraudulent use of your CNIC.
• Helps manage family numbers under correct owners.
• Secure your mobile number if you’re handing it over to someone else.
• Prevents unwanted liabilities linked to SIM misuse.
