How to Send SMS to DND Numbers Easily
Have you ever tried sending a message and it didn’t go through? Maybe the person had their number on DND! 📵 DND stands for “Do Not Disturb,” which means they don’t want to receive promotional messages. But what if an important update or alert needs to be delivered? That’s where Bulk SMS to DND comes into the picture.
Bulk SMS to DND allows businesses to send permitted message types, such as transactional or service-related SMS, to DND numbers while following TRAI and DLT rules.
What is DND?
DND (Do Not Disturb) is a service by TRAI (Telecom Regulatory Authority of India) that stops people from getting promotional messages and calls. When someone activates DND on their mobile number, they block ads like:
- Product offers
- Discount messages
- Marketing calls
People register their mobile numbers on DND to stop unwanted marketing messages. But this can be a problem for businesses who want to send helpful or urgent updates.
Why Can’t You Send SMS to DND Numbers?
By law in India, you cannot send promotional messages to DND-registered numbers. Doing this can get your business into trouble. There are fines and even blacklisting!
But not all messages are the same. Some messages are allowed even on DND numbers.
Types of SMS Messages
There are two main types of SMS messages:
| Type of SMS | Can You Send to DND? | Examples |
|---|---|---|
| Promotional SMS | ❌ No | Discounts, offers, ads |
| Transactional SMS | ✅ Yes | OTP, booking confirmations, alerts |
| Service Implicit SMS | ✅ Yes | Reminders, updates for customers |
| Service Explicit SMS | ✅ Yes (with consent) | Newsletters, marketing to opted-in users |
