Overview

What is Bulk SMS Service?

As a dedicated bulk sms service for business, our platform serves as an enterprise communication channel that enables companies to send high volumes of text messages to mobile numbers across India and beyond. As a leading bulk sms provider india, we ensure it remains one of the most dependable ways to deliver time-critical information — from One-Time Passwords (OTPs) and transaction alerts to promotional offers — directly to a customer's phone without needing an internet connection. In India, bulk SMS services are governed by TRAI through the DLT (Distributed Ledger Technology) framework, which mandates sender verification and curbs unsolicited messaging.

Who is this for?

IT companies, SaaS products, app developers and platforms that send verification codes and notifications to their users.

Bulk SMS and OTP API for IT and SaaS Companies

Bulk SMS for IT & SaaS Companies

For software products, SMS is part of the user journey: sign-up verification, two-step login and account alerts. Those messages have to arrive in seconds, every time, at whatever volume your user base reaches.

Nexcomm's API is built for developers, with HTTP and HTTPS wrappers, XML and JSON support, SMPP connectivity and webhooks that return delivery reports to your system.

How Bulk SMS Works

Step 1

DLT Registration

Register your business and sender headers (e.g., NEXCOM) on a TRAI-approved DLT platform to stay compliant and legally authorized to send messages.

Step 2

Upload Contacts

Import your customer list via Excel or CSV, or connect your existing systems through our robust API for seamless data sync.

Step 3

Compose Message

Write your message content or select from pre-approved DLT templates for transactional or promotional communication.

Step 4

Instant Delivery

Once sent, our intelligent routing engine dispatches messages through the fastest available operator path — Airtel, Jio, Vi, or BSNL.

Step 5

Real-time Reports

Monitor delivery outcomes — Delivered, Failed, or DND — live on your dashboard as they happen.
