WhatsApp users in Pakistan have been urged to ensure that their accounts remain linked to active and registered SIM cards, amid growing concerns over the potential loss of access to accounts associated with inactive or deactivated mobile numbers.
According to an advisory issued by Pakistan Telecommunication Limited (PTA) to mobile users, WhatsApp accounts connected to inactive, blocked, unregistered, or deactivated SIM cards could become inaccessible, potentially putting personal conversations, contacts, and digital identities at risk.
The warning highlights the importance of maintaining an active mobile number for WhatsApp verification and account recovery purposes. If a SIM card linked to a WhatsApp account is deactivated or reassigned, users may face difficulties accessing their accounts or restoring them on a new device.
Authorities have advised users to immediately verify whether their WhatsApp account is connected to a valid and active SIM card. Individuals using numbers that are no longer active have been encouraged to migrate their WhatsApp accounts to a verified SIM without delay.
The advisory also recommends that users visit their nearest mobile network franchise or customer service centre if biometric verification or SIM confirmation is required. This step can help ensure that the registered number remains active and associated with the rightful owner.
Cybersecurity experts have long warned that inactive mobile numbers can create security vulnerabilities, particularly when they are recycled and assigned to new subscribers. In such cases, account recovery mechanisms tied to the old number may expose users to the risk of losing control of their messaging accounts.
WhatsApp relies on mobile numbers as the primary method of account verification, making the status of the linked SIM card a critical component of account security. Users are therefore encouraged to regularly check the status of their registered number and update their account information whenever necessary.
The latest advisory serves as a reminder for millions of WhatsApp users to take proactive steps to safeguard their accounts, protect personal data, and avoid disruptions to their digital communications.
Mobile users are advised to act promptly to ensure uninterrupted access to WhatsApp and other services linked to their registered phone numbers.
