On November 28, 2025, the Department of Telecommunications (DoT) issued a directive requiring application-based communication services, including WhatsApp, Telegram, Signal, Arattai, Snapchat, ShareChat, JioChat, and Josh, to implement active SIM linkage for user access.

This measure, known as “SIM binding,” mandates that these platforms can only be used with a specific, active SIM card, effectively eliminating anonymous or multi-device usage. The directive aims to strengthen user traceability and enhance compliance with national security and data protection norms.
