India’s Department of Telecommunications has ordered major messaging apps to implement continuous SIM binding and frequent web re-authentication to curb fraud, with compliance expected in early 2026. The directive applies to app-based communication platforms that use mobile numbers as identifiers, including WhatsApp, Telegram, Signal, Snapchat, ShareChat, JioChat, Josh, and regional players like Arattai. Apps must continuously verify that the SIM linked to the registered number is present and active on the device, not just at account setup. Additionally, web sessions (e.g., WhatsApp Web) must auto-logout every six hours, forcing users to re-link via QR code.
