"DLT, or Distributed Ledger Technology, is a broad term that refers to technologies such as blockchain, which use decentralized networks to record and handle data. However, when discussing DLT in the context of SMS (Short Message Service), it generally refers to the regulatory setup and technology that help manage and protect SMS traffic. In certain areas, especially in India, DLT is used to ensure that SMS communications follow regulations and avoid spam and fraudulent activities. This system requires companies to register their SMS message templates and sender details with a DLT platform. This process allows for the monitoring of SMS traffic and ensures that messages are genuine and meet the standards set by regulatory bodies. To sum up, DLT for SMS involves using both technology and rules to control and secure SMS communications, ensuring they are real and meet legal standards."
