What is bulk SMS and how does it work?

Our bulk SMS platform enables businesses to send Transactional SMS, Promotional SMS, OTP SMS, Voice, and WhatsApp messages. We offer API integration, DLT compliance, and real-time delivery reports.

Can I send SMS to DND numbers?

Yes, but only transactional or service-based messages can be sent to DND numbers. Promotional messages are blocked for users registered under DND preferences.

What is a transactional SMS (Service Implicit) in India?

Transactional SMS refers to messages sent to customers containing important information such as OTPs, alerts, or order confirmations. These messages are delivered even to DND numbers and are regulated under TRAI guidelines.

How do you protect my data and privacy?

We use SSL encryption, secure APIs, and follow TRAI's DLT protocols to ensure your data and messages are protected during transmission.

What is promotional SMS (Service Explicit) and when can it be sent?

Promotional SMS is used for marketing offers, discounts, and advertisements. In India, promotional messages can only be sent to non-DND numbers and within permitted time windows, typically 10 AM to 9 PM as per TRAI regulations.

Is bulk SMS secure for sending OTPs?

Yes, bulk SMS is widely used for OTP delivery due to its speed and reliability. However, it should be used with secure APIs and proper authentication mechanisms.

What is DLT registration and why is it required?

DLT (Distributed Ledger Technology) registration is a mandatory process introduced by TRAI to prevent spam SMS. Businesses must register their sender ID, templates, and headers on a DLT platform before sending SMS in India.

How much does bulk SMS cost in India?

Bulk SMS pricing in India typically ranges from ₹0.10 to ₹0.25 per SMS, depending on volume slabs.

How can I send SMS using API?

You can send SMS via API by integrating your system with an SMS gateway provider. Most providers offer REST APIs where you send parameters like mobile numbers, message content, and sender ID to trigger SMS delivery.

What is the difference between Service Implicit SMS and Service Explicit SMS?

Service Implicit SMS is used for important alerts and is delivered to all users, including DND numbers. Service Explicit SMS is used for marketing and is restricted to non-DND users and specific time windows.
