New Delhi, Nov 18
The Telecom Regulatory Authority of India (TRAI) has directed all access providers to mandate pre‑tagging of all variable components in SMS content templates used for commercial communication, the government said on Tuesday.
Variable components such as URLs, application download links and callback numbers that change depending on recipients or over time must now be explicitly tagged, an official statement said.
Absence of predefined tagging allowed unregistered or malicious URLs, app links, and callback numbers to be inserted into approved templates without detection.
