Sim-Binding: India's New Rule for Messaging Apps Sparks Debate

• India's telecom department mandates 'Sim-Binding' for messaging apps like WhatsApp, Telegram, and Snapchat by February 2026. If the SIM used for account creation is removed, the app will stop working on that phone; web versions will also log out every 6 hours.
• The Cellular Operators Association of India (COAI) supports Sim-Binding, stating it will create an unbreakable link between user, mobile number, and device, helping prevent spam, fake calls, and online fraud.
• Broadband India Forum (BIF) and IAMI oppose the rule, calling it "problematic" and "clear overreach," arguing it was issued without consultation and may not effectively stop fraud, impacting various digital sectors.
• COAI clarifies that Sim-Binding won't cause issues for users abroad (can use dual SIM) or for business workflows, and web version logouts are standard security practice (like banking apps).
• COAI asserts that no new data is collected; the app only verifies the linked SIM, enhancing security without infringing on privacy, similar to UPI.

Why It Matters: India's sim-binding rule for messaging apps seeks to curb fraud, but its impact is debated.
