Frequently Asked Questions

Everything you need to know about our Bulk SMS services in India.

Bulk SMS is the simultaneous dispatch of large volumes of SMS messages to multiple recipients at once. Businesses use it for marketing campaigns, alerts, OTPs, and customer notifications. You upload your contact list, create your message, and our platform routes it instantly through telecom operators to reach all recipients in seconds.
Promotional SMS is used for marketing and can only be sent between 9 AM–9 PM to non-DND numbers. Transactional SMS carries critical information (OTPs, order updates, alerts) and can be sent 24/7 to all numbers including DND. OTP SMS is a sub-category of transactional SMS, specifically for one-time passwords, and has the fastest delivery priority on our network.
DLT (Distributed Ledger Technology) is a mandatory TRAI regulation for all commercial SMS senders in India. You must register your business entity, Sender IDs, and message templates on the DLT platform. Without DLT registration, your messages will not be delivered. iBACT Digital assists you through the entire DLT registration process at no extra cost.
Integration takes minutes with our REST API. Sign up, get your API key from the dashboard, and make a simple HTTP POST request β€” as shown in our code examples above. We provide official SDKs for PHP, Python, Node.js, and Java, plus detailed documentation with example code for common use cases like OTP, notifications, and campaign blasts.
Most messages are delivered within 3–5 seconds of submission. OTP messages have the highest priority and are typically delivered in under 5 seconds. Large campaigns of 1 lakh+ messages are processed and dispatched in parallel β€” typically completing within 10–15 minutes depending on volume. Real-time delivery reports let you track exactly when each message was delivered.
Absolutely. Our OTP SMS gateway is optimized specifically for authentication workflows β€” login, payment verification, account creation, and two-factor authentication. It operates 24/7 on all networks with a dedicated high-priority route, ensuring your users receive OTPs within seconds even during peak traffic. You can integrate it via API or use our pre-built OTP widgets.
