Why You Should Block a Lost or Stolen SIM

Blocking a lost or stolen SIM card is essential to prevent unauthorized access to your calls, messages, and financial transactions. A stolen SIM could be used for fraud, illegal activities, or even identity theft. That’s why it’s crucial to act quickly and block it immediately.

Ways to Block a SIM Card Online in Pakistan

There are multiple ways to block your SIM card online or through customer service. Here are the most effective methods:

    • IMEI number (if blocking a mobile device)
    • Reason for blocking
  4. Submit the Request and save the reference number for tracking.
  5. Processing Time: PTA typically blocks the SIM within 24 hours after verification.

2. Block Your SIM Through Your Telecom Operator

Every mobile network operator in Pakistan provides SIM blocking services. You can request a block through their official helpline.
