SMS for India

Enterprise SMS & Bulk SMS Service

DLT-ready bulk SMS for India — OTPs on their own fast lane, campaigns that never block each other, and a report for every number you send to.

Features

Built for how India sends SMS

Compliance, speed where it matters, and clear answers about every message.

DLT-ready by design

Send on your registered headers with approved templates — the platform picks the template that matches your message.

OTP fast lane

API messages like OTPs travel in their own lane, so they never wait behind a campaign.

Fair queue for campaigns

Campaigns take turns, so one large send never blocks the rest.

Personalised from a sheet

Upload Excel or CSV and map a column to each {#var#} — every customer gets their own details.

Review, then send or schedule

One review screen shows the audience, message and SMS count before anything goes out.

Hindi and Indian languages

Unicode SMS in every Indian script, with the SMS count shown as you type.

Every message accounted for

All Sent shows each number’s status; numbers that couldn’t be sent are listed with the reason.

One opt-out list

Opt-outs are honoured on SMS, WhatsApp, RCS and voice — from the panel and the API.

API, webhooks and integrations

HTTP API (JSON or XML), delivery reports by webhook, and connectors for WebEngage and LeadSquared.

Transactional, service or promotional?

Every SMS template in India is registered under a category on DLT — and the category decides who it can reach.

1

Transactional

Critical alerts: OTPs, bank transaction alerts.

Reaches every customer, including DND

2

Service

Updates customers expect: orders, deliveries, appointments, bills.

Reaches customers who have a relationship with you

3

Promotional

Offers, launches, re-engagement.

Only customers who haven’t blocked promotions, in allowed hours

Bulk SMS questions, answered

What do I need to send bulk SMS in India?
A registration on the DLT platform with your business (the principal entity), a sender ID (header) and approved message templates. Promotional messages also need the right consent and can only go out in the allowed hours. TextNation helps you get headers and templates set up and picks the approved template when you send.
What is the difference between transactional, service and promotional SMS?
Transactional messages are critical alerts such as OTPs and bank transaction alerts. Service messages are updates customers expect — order, delivery or appointment updates. Promotional messages are offers and marketing, and only reach people who haven’t blocked them under DND preferences. Each template is registered under one of these categories on DLT.
Will a big campaign slow down my OTPs?
No. On TextNation, messages sent through the API — like OTPs — travel in their own fast lane, and campaigns take turns, so one large send never holds up the rest.
Can I send personalised SMS from an Excel sheet?
Yes. Upload an Excel or CSV file, pick the approved template, and choose which column fills each {#var#} in the template. Every recipient gets their own name, amount or date.
How do I know which messages were delivered?
Every message appears in All Sent with its delivery status, and numbers that couldn’t be sent are listed with the reason. You can export any list to Excel or CSV, see usage reports by day and month, and receive delivery reports on your own system by webhook.
Can I send SMS in Hindi and other Indian languages?
Yes. Messages in Hindi and other Indian scripts are sent as Unicode, which fits 70 characters per SMS instead of 160. Use our free SMS character counter to see exactly how many SMS a message will take.
How is SMS priced?
Pricing depends on your volumes and the kind of traffic you send. Talk to us for a quote.
