As we know TRAI has made it compulsory to approve an organization/brand from DLT before sending Bulk SMS. If you have not yet registered your organization/brand on DLT, do it hurriedly. To avoid scams, all basic features of Bulk SMS are required to get approved first by DLT i.e organization, sender ID, and even content template. If you are our existing customers and have not been approved by DLT yet, your SMS will stand failed by 2021. A content template is actually the message/ text body that you as a company or Entity require to send your consumers or clients in the form of bulk SMS. Enterprises and businesses are bound to register their message content on the DLT operator as a content template. There are four routes for Bulk SMS in DLT i.e Promotional, transactional, Service Explicit, and Service Implicit.
