PTA to block WhatsApp accounts linked to inactive SIMs
Why PTA is targeting inactive SIMs
The regulator says inactive mobile numbers can create security risks because their original users may no longer control them.
Once a SIM becomes inactive or is cancelled, the mobile number can eventually be issued to another subscriber. This creates a potential risk if a WhatsApp account remains connected to the old number.
The new user of the number could potentially receive verification codes and gain access to an account that is still associated with that number. PTA has linked its latest action to efforts to prevent fraud, misuse of mobile numbers and other unlawful activities.
WhatsApp accounts could become inaccessible
PTA has warned that WhatsApp accounts linked to blocked, cancelled, inactive or unregistered SIMs may become inaccessible. The authority has repeatedly advised users not to wait until they are unexpectedly logged out before taking action.
In an earlier advisory, PTA urged users to ensure that their WhatsApp accounts remain connected to active and properly registered SIMs. The latest warning again highlights the importance of keeping mobile numbers active and under the control of their users.
What WhatsApp users need to do
Users who are still using an active SIM connected to their WhatsApp account generally do not need to change their number. However, people who have changed their mobile numbers or stopped using their old SIMs should update their WhatsApp accounts.
WhatsApp provides a Change Number feature that allows users to move their accounts to a new mobile number. PTA has advised affected users to use this option promptly rather than continuing to use an account linked to a number they no longer control.
Check whether your SIM is still active
Users should first check whether the mobile number registered with their WhatsApp account is still active. They should also ensure that the SIM is properly registered and remains under their control.

PTA has previously advised users to complete biometric and SIM verification where required. People who need assistance with verification can contact their mobile operator’s franchise or customer service centre.
Why old mobile numbers can become risky
Many people continue using WhatsApp on numbers they stopped using years ago. The problem may not be immediately visible because WhatsApp can continue working even when the SIM is no longer being used regularly. However, the situation can become complicated once the number is cancelled or reissued.
If another person receives the same number, the old WhatsApp account could create security and privacy concerns. This is why PTA is asking users to regularly check the status of the mobile number connected to their accounts.
PTA steps up digital security measures
The latest warning is part of PTA’s broader effort to strengthen mobile and digital security. The authority has increasingly stressed that a mobile number is not simply a communication tool but is also linked to a user’s digital identity.
WhatsApp accounts, online services and other digital platforms can remain connected to mobile numbers for long periods. Keeping those numbers active and properly registered can therefore help users maintain control over their digital accounts.
Users urged not to delay
PTA has said action against WhatsApp accounts associated with inactive mobile numbers could begin at any time. Users who know that their WhatsApp number is no longer active should therefore update their accounts without waiting for access problems.
Those who are unsure about their SIM status should verify it through their mobile operator or seek assistance from a customer service centre. Taking action while the old number is still accessible can make it easier to transfer the WhatsApp account to a new active number.
