How it works

## How an OTP reaches your customer

One API call. Everything between your server and the customer's phone is handled for you.

1.  ### Your app sends the OTP
    
    One API call with the mobile number, your DLT-registered sender ID and template, and the message.
    
2.  ### DLT checks the message
    
    The SMS is scrubbed against your registered sender ID and template on TRAI's DLT platform before any operator accepts it.
    
3.  ### The operator delivers it
    
    It is routed to the customer's operator; if a route fails, the platform retries through an alternate one, so an OTP is not lost to one outage.
    
4.  ### You get the delivery report
    
    The delivery status comes back to your webhook and dashboard, and the SMS is billed at your slab's rate.
    

## One rate card, set by your monthly volume

The more you send in a month, the lower the rate - and the whole month is billed at the rate of the slab you reach.

## DLT-compliant by default

-   ### DLT registration
    
    Every business sending SMS in India registers its entity, sender IDs and templates on an operator's DLT portal - a one-time ₹5,000 + GST entity fee paid to the operator. We help you through it.
    
-   ### Links and numbers
    
    Since 1 October 2024, a URL in an SMS must be whitelisted in your DLT template, and public link shorteners are blocked. We check templates before you go live.
    
-   ### Check the number first
    
    The MNRL Check API tells you if a number is on the Mobile Number Revocation List, so OTPs never go to a disconnected or reassigned number.
    

APIs

## The compliance API behind SMS delivery

Check a number against the Mobile Number Revocation List before you message it, so OTPs and alerts never reach a disconnected or reassigned number.

[MNRL Check API](/apis/mnrl-check/ "Check whether an Indian mobile number appears on the Mobile Number Revocation List, flagging disconnected numbers before they are reassigned.")

## SMS pricing questions

How much does an SMS cost?

From ₹0.20 per SMS at up to 24,999 a month, falling by slab to ₹0.18, ₹0.16, ₹0.14 and ₹0.12, and ₹0.10 from 25 lakh a month. Prices are before 18% GST. Above 50 lakh a month, we price it with you.

How does the slab pricing work?

Your monthly volume decides your slab, and every SMS that month is billed at that slab's rate. Sending 1,00,000 SMS in a month puts all of them at ₹0.16.

What counts as one SMS?

One 160-character part. English text longer than 160 characters is sent in parts of 153; Hindi and other Unicode scripts fit 70 characters, or 67 per part. Each part is billed as one SMS.

Do I need DLT registration?

Yes. TRAI requires every business sending SMS in India to register its entity, sender IDs and message templates on an operator's DLT portal. The one-time entity fee of ₹5,000 + GST is paid to the operator, and we help you register.

Why are Twilio and Plivo so much more expensive for India?

They send SMS to Indian numbers over the international route, which operators charge at international rates. FastKYC sends over domestic DLT routes.

What happens when a network fails?

Messages are routed for fast delivery, and if one network fails the platform retries through alternate operators, so an OTP is not lost to a single carrier outage.

Can I check a number before I message it?

Yes. The MNRL Check API tells you whether an Indian mobile number is on the Mobile Number Revocation List, so OTPs and alerts are not sent to disconnected or reassigned numbers.

How do I integrate the SMS API?

Through a REST API that works from any major programming language. Delivery reports arrive on your webhook and in the dashboard in real time once you are live.
