Govt orders SIM-linked logins for WhatsApp and Telegram to curb cyberfraud

In a bid to shore up telecom security and curb cyberfraud, the central government has mandated that major messaging apps tether user accounts to the SIM card used at registration. The new rules require services to maintain continuous SIM linkage and to block access if the original SIM is not present or detectable, with six-hour session timeouts enforcing periodic re-authentication.

On desktop versions, apps will automatically log users out every six hours, and re-entry will require scanning a fresh QR code. Smartphone access will be restricted to the original SIM card used for signup, a move authorities say will help prevent fraud and misuse across borders or from devices not linked to the registered number.

Officials say the move aims to prevent cross-border misuse and to enhance telecom cybersecurity. The policy follows earlier Telecom Cyber Security Rules notified in 2024 and updated in 2025, reflecting a broader push toward stricter digital identity checks for popular messaging platforms.

Critics warn the measures could complicate legitimate business communications, hinder multi-device usage, and raise privacy questions about data handling and device monitoring. The timing of enforcement and the exact rollout details—such as exemptions for corporate accounts or emergency scenarios—remain to be clarified.

For users, the news signals upcoming changes in how they access chats on different devices. Platforms say they will publish guidance as rules come into effect, and users should monitor official notices for timelines or exceptions.
