TRAI's new anti-spam measures could delay OTP delivery starting September 1

Telecom companies have been directed by TRAI to stop the transmission of messages containing URLs, OTT links, APK files (Android application packages), or call-back numbers unless they have been whitelisted.

The Telecom Regulatory Authority of India (TRAI) has introduced new rules to combat the spread of spam and phishing attacks through SMS. These rules will take effect from September 1 and require institutions such as banks and app-based services to register and whitelist their numbers by August 31 in order to send one-time passwords (OTPs). The new system will also scan messages for suspicious links, potentially causing delays in OTP delivery to users.
