SIM binding for WhatsApp: India imposes six-hour logouts to curb fraud
New rules require SIM-linked authentication for messaging apps like WhatsApp, with six-hour web session logouts and continuous SIM verification to boost cybersecurity.
India is set to implement a SIM binding policy for popular messaging apps by February 2026, requiring users to continuously verify their registered SIM cards. The rule aims to block access when a SIM is deactivated and to curb cyber fraud by ensuring apps do not operate on unlinked numbers. Web versions will automatically log out after six hours of inactivity, with re-authentication required for continued use.
Under the new directive, platforms such as WhatsApp and Telegram must ensure services stay tied to the original SIM used at registration. If the SIM is not present, access could be blocked, and desktop users would need to re-scan a QR code to resume on the web after a six-hour session. Smartphone access will be restricted to the registered SIM, a move aimed at preventing misuse from abroad or from spoofed numbers.
The notification was issued in late November 2025 and takes effect immediately. Officials say the measures strengthen telecom cybersecurity and protect users from fraud, even if they introduce added friction for some everyday tasks.
Industry observers say the policy could affect millions of users and reshape how people use messaging apps for work and personal life. While supporters welcome added security, critics warn of inconvenience for travelers and multi-device users. The government emphasises that the goal is stronger protection for digital communications.
