PTA has started blocking WhatsApp accounts associated with inactive SIM cards as part of efforts to reduce the risk of misuse and strengthen account security for mobile users across Pakistan. The latest measure follows an awareness campaign encouraging users to ensure that their WhatsApp accounts remain linked to active mobile numbers that they currently own and use. PTA has advised individuals to review their account settings and update their registered numbers if the SIM cards previously connected to their WhatsApp accounts have been deactivated, cancelled, or are no longer under their control.
According to officials, the initiative is intended to address security concerns that can arise when inactive mobile numbers are returned to telecom operators and later reassigned to new subscribers. If a WhatsApp account continues to remain registered on a number that has already been reissued, there is a possibility that the previous account holder could lose access to the account or face unauthorized access if the number is activated by another user. By identifying and blocking WhatsApp accounts connected to inactive SIM cards, PTA aims to reduce these risks and encourage users to keep their account information updated. The authority has emphasized that maintaining an active and personally controlled mobile number for WhatsApp registration is an important step in protecting private conversations, contacts, and account settings from unintended access.
PTA has also urged mobile phone users to verify the status of their SIM cards and ensure that their WhatsApp accounts are linked only to numbers they actively use. Users who have switched to a new mobile number have been encouraged to use WhatsApp’s Change Number feature, which allows account information, contacts, and chat history to be transferred to the current number while maintaining account continuity. Officials noted that using this built in feature can help users avoid disruptions while reducing the possibility of account misuse associated with outdated or inactive mobile numbers. The authority continues to encourage the public to regularly review their account settings and mobile registration details to maintain better digital security and ensure that messaging accounts remain connected to valid and active SIM cards.
The latest action follows previous advisories issued by PTA regarding the security implications of keeping WhatsApp accounts registered on inactive or cancelled SIM cards. Those earlier warnings highlighted the importance of updating account information whenever a mobile number is changed or disconnected to prevent future complications. Through this initiative, PTA is reinforcing awareness around responsible account management and encouraging users to take timely action before inactive numbers are reassigned. The measure reflects continued efforts to promote safer digital communication practices and reduce opportunities for unauthorized account access that may result from outdated mobile registrations. By keeping WhatsApp accounts linked to active SIM cards under their direct control, users can improve the security of their accounts and reduce the likelihood of potential misuse.
