What is DLT SMS, and why is it required in India?

DLT SMS (Distributed Ledger Technology SMS) is TRAI’s blockchain-based system to regulate commercial SMS in India, mandatory since TCCCPR 2018. It requires businesses to register entities, headers, and templates with operators to curb spam (e.g., via smsgatewaycenter.com/dlt-sms/). SMSGatewayCenter simplifies DLT compliance, making your SMS gateway campaigns legal and effective.
