Pakistan Telecommunication Authority (PTA) has issued an important advisory for WhatsApp users across Pakistan, warning that accounts linked to inactive, blocked, deactivated, or unregistered SIM cards may soon become inaccessible, stressing that mobile numbers now form a key part of a user’s digital identity and must remain active and properly verified to avoid service disruption. The advisory marks a notable escalation in PTA’s ongoing drive to tighten the link between verified mobile identities and access to digital communication platforms, signalling that the days of maintaining WhatsApp accounts on dormant or unregistered numbers may be numbered for millions of users across the country.
Users whose WhatsApp accounts are connected to invalid or inactive SIM cards risk losing access to their accounts, chats, contacts, and other personal data, and PTA has urged citizens to immediately verify whether the mobile number linked to their WhatsApp account is registered in their name and associated with an active SIM. The telecom regulator further advised users to migrate their WhatsApp accounts to a verified SIM if their current number has become inactive or unregistered. This is particularly relevant in Pakistan’s context, where it is common for users to retain WhatsApp accounts on numbers that may have been inactive for months, or on SIM cards that were purchased and registered informally before stricter biometric verification norms came into force.
PTA also directed users to visit their nearest mobile franchise or customer service centre if biometric verification or SIM re-verification is required, noting that biometric verification remains essential for securing communication services and preventing the unauthorised use of digital identities. As part of its awareness campaign, PTA emphasised the importance of digital security and urged citizens to stay informed through its official platforms and digital assistant service available on WhatsApp at 0315-0055055, running the campaign under the slogan: “Protect Your WhatsApp. Protect Your Digital Identity.” The campaign represents one of PTA’s more consumer-facing digital outreach efforts in recent memory, using WhatsApp itself as a channel to communicate the risks of operating through unverified numbers on the same platform.
The advisory fits into a much wider pattern of regulatory action that PTA has been steadily building around SIM compliance and digital identity verification. Under 2026 PTA regulations, citizens are allowed a maximum of five voice SIM cards and three data SIM cards per Computerised National Identity Card, with automated systems in place to block non-compliant SIMs without warning, and citizens are encouraged to regularly check all SIMs registered against their identity card by sending their Computerised National Identity Card number via short message service to 668 or through the official portal at cnic.sims.pk. With WhatsApp now effectively treated as an extension of a user’s verified mobile identity, PTA’s latest move signals that digital access and SIM compliance are increasingly being treated as two sides of the same regulatory concern.
