Distributed Ledger Technology (DLT) is a block-chain based registration system. According to TRAI (Telecom Regulatory Authority of India), telemarketers have to be registered in the DLT platform. It is being issued in the public interest to control the SMS spam from various marketing firms.
The DLT platform is a block-chain based registration system adopted to keep records of all transactions made between network participants. It’s aimed at creating more transparency and reducing the incidence of spam and fraud.

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

Other Bank related messages such as amount debited/ credited, account status, etc. cannot be sent via Transactional route. This route can be used by all Banks including National/ Scheduled/ Private/ Government/ MNC.
Transactional route can be used only by Banks for just sending OTP SMS.

2.Service Implicit: Service Implicit route can be used by business and companies for sending important SMS related to products and service updates. Examples are website/app OTP, payment alerts, purchase details, order delivery, and all other informative messages.

3.Service Explicit: Service Explicit route can be used for sending marketing related SMS to the customers after receiving their permission. If a customer gives permission to receive promotional SMS, then the messages will come under the Service Explicit category.

4.Promotional:Promotional SMS includes the marketing related SMS which can be delivered only to the NonDND numbers. SMS sent to promote products and services will come under this category.

Content Template is the message text which you have to submit on the DLT portal. It is the actual text of your SMS that has to be approved by DLT before sending it to your customers.
Content Template has to be submitted for every single message you want to send to your customers in India.
Note:Content Template is mandatory for all type of SMS routes – Transactional, Service Implicit, Service Explicit and Promotional.

Consent Template is used for taking customer’s permission before sending them promotional SMS. In simple words, if a business wants to send promotional SMS to its customers, it has to first submit Consent Template on the DLT platform which can be mapped to promotional messages at the time of approving Content Templates.
If you are sending SMS only from the Service Implicit route, then you just need to submit Content Template on the DLT portal. But, if you are sending marketing related SMS, then at first you have to submit Consent Template (Promotional SMS permission) and after it is approved, you have to submit Content Template (actual SMS text).
Note:Consent Template is not required for Service Implicit route. It is mandatory for Service Explicit & Promotional route only
