How to choose an SMS provider
Here are the key factors you should consider when choosing an SMS provider.
Easily integrate SMS with your existing tech stack
We want to keep your operations running smoothly. That’s why our platform is easy to work with. Choose from a wide range of integrations to build and add on top of our SMS API, and easily configure them with your existing systems.
DLT (Distributed Ledger Technology) is TRAI's blockchain-based regulatory system for commercial messaging in India. Every business that sends bulk SMS must register on the DLT portal and obtain an Entity ID, Sender ID (Header), and approved message templates before they can send any commercial SMS. DLT ensures accountability and protects consumers from spam.
DLT registration is mandatory under TRAI regulations for all businesses sending commercial SMS in India. Without it, your messages will be blocked by telecom operators. Registered businesses benefit from: higher delivery rates, protection from blacklisting, legal compliance, and consumer trust. Non-compliance can result in permanent sender ID suspension.
Step 1: Create an account on any DLT portal (Vilpower, Airtel DLT, Jio Trueconnect, or Vi DLT). Step 2: Upload business documents — GST certificate, PAN card, and certificate of incorporation. Step 3: Verify your entity and receive a unique Entity ID. Step 4: Register your Sender ID (Header) and message templates. ConnexBetter provides free DLT registration assistance to all customers.
