Transactional SMS Service Provider in India

Transactional SMS refers to automated, template-based text messages sent to customers to deliver essential, non-marketing operational information such as banking alerts, OTP codes, order confirmations, ticket PNR updates, and payment receipts. Unlike promotional messages, transactional messages are delivered 24 hours a day, 7 days a week, across all Indian telecom networks to both DND and non-DND numbers.

Under TRAI DLT regulations: 1) Transactional route is reserved exclusively for scheduled commercial banks and financial institutions for OTPs and transaction alerts; 2) Service Implicit covers essential operational notifications arising from an existing customer relationship (e-commerce OTPs, booking updates, account alerts) delivered 24x7 to all numbers; 3) Promotional SMS covers marketing offers and discounts, which can only be sent to non-DND subscribers between 10:00 AM and 9:00 PM IST.

Yes. Transactional and Service Implicit SMS routes are legally permitted by TRAI to deliver messages to numbers registered on the National Do Not Disturb (DND/NDNC) registry 24x7 without any time restrictions, provided the content matches an approved DLT template.

To send Transactional SMS, your business must: 1) Register as a Principal Entity (PE) on a telecom DLT portal (Jio, Airtel, Vi, or BSNL); 2) Add SMSINDIAHUB as your registered Telemarketer (TM ID: 1702157373640103575); 3) Register a 6-character alphabetic Sender ID (Header); and 4) Submit and approve content templates with dynamic variables ({#var#}).

SMSINDIAHUB connects directly with Tier-1 telecom operators (Airtel, Jio, Vodafone Idea, and BSNL) through high-throughput SMPP pipes. Our intelligent routing algorithm delivers transactional alerts and OTPs with an average latency of under 5 seconds and guarantees a 99.95% gateway delivery SLA.

Integration requires only a few minutes. SMSINDIAHUB provides standard RESTful HTTP APIs with pre-built code snippets and SDKs for PHP, Python, Java, Node.js, C#, and cURL. Simply pass your API Key, approved 6-character Sender ID, DLT Template ID, recipient mobile number, and template message text.

Dynamic variables represented as {#var#} are placeholders inside an approved DLT template that allow you to insert personalized information like OTP codes, customer names, transaction amounts, account numbers, or tracking URLs into each SMS. The static text of your message must match the approved template exactly.

When a customer completes a checkout or payment on your website or POS terminal, your backend triggers an automated API call to SMSINDIAHUB passing the transaction details. The system generates an immediate transactional confirmation SMS with payment reference, amount, and invoice link delivered to the customer within seconds.

Yes. SMSINDIAHUB provides live delivery reporting on your web dashboard, including operator submit timestamps, carrier delivery receipts, and error failure reasons. Additionally, you can configure automated webhook callback URLs to receive real-time delivery status updates directly into your database.

SMSINDIAHUB employs automated multi-carrier smart load balancing across multiple telecom operator gateways. If a specific carrier experiences routing latency or downtime, our system instantly shifts traffic to active backup pipes without human intervention, ensuring zero transactional drop-offs.
