The menace created by unsolicited SMS is increasing at a thunderous rate. Even after taking preventive measures for spamming and imposing the Do Not Disturb (DND) activation facility, there is no relief from this rattrap. Till date, customers are suffering from uninvited messages, unwanted SMS as well as falling prey to phishing attacks. In order to guard consumers’ interest, TRAI has notified The Telecom Commercial Communication Customer Preference Regulation (TCCCPR) 2018 and has declared certain guidelines to regulate fraudulent practices and bring an end to spam messages. In accordance with the new regulations introduced by TRAI, the companies systems will be managed using Distributed Ledger Technology (DLT).

According to which, every individual/business needs to register with the telecom operators on the DLT platform in order to continue sending SMS to their clients and customers without interruption. Each Individual/Business(Principal Entity) and Telemarketer will be accountable to telecom operators(Access Providers) who will be directly accountable to TRAI.
