India’s Department of Telecommunications (DoT) has issued a sweeping new directive mandating SIM-binding for all app-based communication services, including WhatsApp, Telegram, Signal, Snapchat, ShareChat, JioChat, Josh and Arattai, as part of a broader push to curb telecom-related cybercrime and identity fraud.
With DoT’s latest directive, the biggest change for users is that messaging apps will no longer work independently of the SIM linked to the registered mobile number. The second change affects users who access these services on a web browser. Web sessions such as WhatsApp Web must now log out automatically every six hours, after which users will need to re-link their device via a QR code.
Responding to this concern, telecom secretary Neeraj Mittal told HT that “we have 90 days to sort out any issues.”
This executive also argued that the six-hour logout rule would be impractical for work-related use, noting that people typically have 8-9 hour workdays and stay signed in across laptops, tablets and other devices, which would force them to log in repeatedly through the day.
All TIUEs providing app-based communication services must submit full compliance reports to the DoT within 120 days of the order’s issuance.
Consumers, however, may also benefit from:
Reduced impersonation and fraud incidents.
Lower risk of accounts being taken over using illegal SIM swaps.
Higher accountability for spam, scams and misuse of social/messaging apps.
