While it’s not mandatory, Plivo recommends registering a sender ID. Messages sent without a registered sender ID are sent with a generic identifier such as “SMS” or “INFO.”
DLT stands for distributed ledger technology. The Telecom Regulatory Authority of India (TRAI) requires any entity who wants to send SMS to register in order to curb unsolicited commercial communication (UCC). Required information includes organizational details, message headers and templates, and required consent information. Read our guide How to Complete DLT Registration for Sending Text Messages in India for information about the process.
Go through the DLT registration process and register a sender ID. Customers that fail to register and use generic sender IDs are charged international pricing for messages sent.
