Frequently Asked Questions About SMS API

Everything you need to know about our SMS API service in India

What is SMS API and how does it work for businesses in India?

SMS API is a programming interface that allows businesses to send text messages directly from their applications, websites, or systems. It works by making HTTP requests to our servers, which then deliver messages through direct connections with Indian telecom operators like Airtel, Jio, Vi, and BSNL. This enables automated messaging for OTP, alerts, promotions, and customer communication.

Is MessageBot SMS service TRAI compliant and DLT integrated?

Yes, MessageBot is fully TRAI compliant with complete DLT (Distributed Ledger Technology) integration. All commercial SMS require registered sender IDs, approved message templates, and proper entity registration. We handle the entire compliance process including DLT registration, template approval, and sender ID verification to ensure your messages are delivered without any regulatory issues.

What is the SMS delivery rate and speed across Indian networks?

We maintain a 99.9% delivery rate across all major Indian telecom operators through direct SMPP connections. Most SMS messages are delivered within 2-5 seconds, with OTP and transactional messages getting priority routing for even faster delivery. Our intelligent routing system automatically selects the best operator path for optimal delivery.

Our SMS pricing starts at ₹0.10 per SMS for enterprise volumes (100,000+ SMS/month). Pricing tiers: ₹0.15 for up to 10,000 SMS, ₹0.12 for 10,001-100,000 SMS, and ₹0.10 for 100,000+ SMS monthly.

Yes, our platform fully supports Unicode SMS for Hindi, Tamil, Telugu, Bengali, Gujarati, Marathi, and other regional Indian languages. Unicode messages allow you to communicate with customers in their preferred language, improving engagement and customer satisfaction. Unicode SMS are charged at 1.5x the standard rate due to character encoding requirements.

What is the difference between transactional and promotional SMS in India?

Transactional SMS are service-related messages (OTP, alerts, confirmations) that can be sent 24/7 to any number without DND restrictions. Promotional SMS are marketing messages that can only be sent to opted-in, non-DND numbers during business hours (9 AM - 9 PM). Transactional SMS have higher delivery priority and different pricing structures.

Our SMS platform is ISO 27001 certified with enterprise-grade security including API key authentication, IP whitelisting, SSL/TLS encryption, secure data storage, regular security audits, and compliance with Indian data protection laws. All message data is encrypted in transit and at rest.

Can I get dedicated sender IDs and custom routing for my business?

Yes, we provide custom sender IDs (6-character alphanumeric) for brand recognition and dedicated routing for enterprise clients. Custom sender IDs require TRAI registration and approval, which we handle on your behalf. Dedicated routing ensures consistent delivery performance and priority handling of your messages.

What kind of analytics and reporting do you provide for SMS campaigns?

Our platform provides comprehensive analytics including delivery status, failure reasons, operator-wise reports, time-based delivery analysis, click tracking for URLs, campaign performance metrics, and real-time dashboards. You can export reports in CSV/Excel format and access data through our reporting APIs.

How do you ensure high SMS delivery rates during peak traffic periods?

We maintain high delivery rates through multiple strategies: redundant operator connections, intelligent load balancing, priority routing for different message types, real-time network monitoring, automatic failover systems, and dedicated infrastructure scaling. During festivals and peak periods, we activate additional capacity to maintain service quality.
