India's Department of Telecommunications (DoT) has mandated that messaging services must operate with active SIM cards linked to users' phone numbers to combat cyber fraud. Popular apps like WhatsApp, Telegram, Signal, and Snapchat must comply with these SIM-binding rules within 90 days. The new regulations also require web sessions to automatically log out after six hours to enhance security and address issues related to long-lived web sessions, which have been exploited by fraudsters. This initiative aims to improve the traceability of accounts and reduce fraudulent activities, particularly phishing schemes and scams. Cyber-fraud losses in India reached ₹22,800 crore in 2024, prompting these Telecom Cyber Security measures. Users roaming with their SIMs will not be affected by the new regulations.
