New SIM-Binding Rules Implemented: WhatsApp, Telegram Users Most Affected

• New SIM-binding rules for messaging apps like WhatsApp, Telegram, and Signal are now fully implemented in India.
• Users must keep their registered SIM in the primary slot; removing or deactivating it will cause the app to stop working.
• WhatsApp Web and desktop versions will auto-logout every 6 hours, requiring re-authentication with an active SIM.
• Government aims to curb cybercrimes and online fraud by linking accounts to KYC-issued SIMs for digital tracing and national security.
• Rules apply to India-registered accounts; foreign travel with Indian SIM in phone is exempt, but removing it for a local SIM may lead to temporary suspension.
