SIM-binding mandate forces changes to WhatsApp use in India

India plans to change how major messaging apps operate under new rules requiring SIM binding and frequent re-verification. The directive obliges platforms to confirm that the original SIM remains active, altering long-standing habits around device switching. Services have 90 days to comply with the order.

The Department of Telecom says continuous SIM checks will reduce misuse by linking each account to a live subscriber identity. Companion tools such as WhatsApp Web will automatically log out every 6 hours. Users will need to relink sessions with a QR code to stay connected.

The rules apply to apps that rely on phone numbers, including WhatsApp, Signal, Telegram, and local platforms. The approach mirrors SIM-bound verification used in banking apps in India. It adds a deeper security layer that goes beyond one-time codes and registration checks.

The change may inconvenience people who use Wi-Fi-only tablets or older devices without an active SIM card. It also affects anyone who relies on WhatsApp Web for work or on multi-device setups under a single number. Messaging apps may need new login systems to ease the shift.

Officials argue that tighter controls are needed to limit cyber fraud and protect consumers. Users may still access services, but with reduced flexibility and more frequent verification. India’s move signals a broader push for stronger digital safeguards across core communications tools.
