How to block a lost or stolen SIM in Pakistan — call your operator's helpline, verify your identity, block the number and get a replacement SIM.
If your phone or SIM is lost or stolen, block the SIM immediately — it protects your bank OTPs, wallet, WhatsApp and social accounts from misuse. You can block it by calling your operator's helpline and verifying your identity, then order a replacement (the number stays the same).
Because so many accounts rely on your mobile number, act fast. This guide covers blocking and replacing the SIM.
From another phone, call your network's helpline — Jazz 111, Zong 310, Telenor 345, Ufone 333 (dial the operator's customer-service number).
Confirm your identity with your CNIC and account details so they know you are the owner.
Ask them to block the SIM so no one can use your number while it is lost.
Change passwords and, where possible, move two-factor authentication for your bank, wallet, email and social apps, since they use this number.
Visit a franchise/service centre with your CNIC and biometric verification to get a replacement SIM on the same number.
Once the new SIM is active, restore WhatsApp and re-enable OTP-based logins.
Call your operator's helpline from another phone, verify your identity with your CNIC, and ask them to block the SIM. Then get a replacement on the same number.
Yes. After identity and biometric verification you can get a replacement SIM on the same number at a franchise or service centre.
Your mobile number receives bank and wallet OTPs and is linked to WhatsApp and many accounts, so a thief could misuse it. Block it as soon as possible.
