India Mandates SIM-Linked Messaging and Six-Hour Web Logouts, Pressuring WhatsApp in Its Largest Market

Officials frame the rules as an anti-fraud step to restore traceability.

Overview

  • Directions issued November 28 give providers including WhatsApp, Telegram and Signal 90 days to enforce continuous SIM–device binding and to auto-log out web and desktop sessions every six hours.
  • The telecom ministry cites rising cyber fraud and reports ₹228 billion (about $2.5 billion) in losses in 2024 as the rationale for the measures.
  • WhatsApp’s deep penetration in India—over 500 million users and heavy use of WhatsApp Business on web and desktop—means small merchants and everyday users could face significant disruption.
  • Industry body BIF and experts at a MediaNama forum say continuous SIM checks are technically unworkable on iOS and modern Android and would break multi-device, cloud-based and remote workflows.
  • Tech policy advisers say companies have limited immediate legal options, with any court challenge needing to show the directions exceed legal scope or violate constitutional protections.
