SIM Binding Regulation to Enhance National Security

The Department of Telecommunications (DoT) has emphasized the importance of SIM binding in light of national security considerations. This move aims to curb rising instances of online fraud and digital arrest scams.

Implementation Details

The DoT had issued guidelines in November 2025, requiring messaging platforms such as WhatsApp, Telegram, Snapchat, Signal, and Arattai to allow SIM binding. This ensures that messaging app accounts are linked exclusively to the physical SIM card used during registration. As a result, the account will only function if the registered SIM is present in the phone.

Compliance Period

Companies were given a 90-day compliance period, ending on February 28, 2026, to implement the changes. Failure to comply may attract penalties under the Telecommunications Act, 2023, the Telecom Cyber Security Rules, and related statutes.

Key Features of SIM Binding

Under the new framework, messaging applications must ensure continued linkage between user accounts and an active SIM card. Unlike the current system, OTP verification is no longer sufficient to allow apps to function. The Centre has clarified that the rules will not impact users who are roaming, as long as their SIM remains active in their device.
