Critics warn DoT SIM-link rule for apps may not curb scams

India's DoT has told major messaging apps to keep accounts continuously linked to an active SIM, aiming to curb scams. Critics say 'true' SIM binding is hard on iOS/Android, may trigger lockouts for travellers and dual-SIM users, and won't stop mule accounts or overseas VoIP scams. Privacy groups warn it could weaken anonymity.
