What is DND SMS?
DND SMS ensures that India’s DND rules are followed for any messages sent to mobile users. Numbers listed under the DND registry are unable to receive certain types of unsolicited marketing or DND promotional SMS. However, they can still get service and transactional messages, including OTPs, account updates, and order alerts.
The solution offered by Vesper Telecom’s DND SMS service provider enables you to send crucial, unobtrusive messages that keep clients informed while upholding total regulatory compliance.
Types of SMS Under DND
DND registry numbers are blocked for these:
Promotional SMS
DND numbers block messages aimed at advertising goods, services, events, or deals.
Examples:
- Discounts, sale alerts, and coupons
- Bank loan offers
- Real estate advertisements
- Travel package promotions
- E-commerce product ads
These are considered promotional DND bulk SMS and cannot be sent without prior consent.
Unsolicited Marketing Messages
This covers any marketing material that the receiver did not specifically agree to.
Examples:
- “Find out your free credit rating today!”
- “Join our gym at 50% off!”
Such messages, including promotional SMS to DND numbers, are seen as intrusive and are blocked for people who have DND turned on.
What is NOT Considered DND (Allowed for DND Numbers)
Certain messages are exempt from DND restrictions because they fall under Transactional or Service SMS, which are essential for customer communication. Among these are:
- OTPs: For banking, login authentication, and secure verification through our OTP service.
- Order/Delivery Updates: Status notifications from e-commerce, logistics, or courier companies.
- Appointment Reminders: For healthcare, salon, or service-based businesses.
- Account Balance Alerts: Banking and finance-related updates.
- Service Notifications: Updates for customers who have already registered for a service.
Vesper Telecom ensures these messages are delivered instantly, securely, and without being blocked, using our reliable SMS gateway provider technology.

Features of DND services
- Once you put your mobile number on the Do Not Disturb (DND) service, your phone number is unavailable to telecom and other companies as a paid database.
- The DND service allows you to pick your preferences for what kind of numbers you want to block or if you wish to stop all types of commercial communication calls and SMS.
- DND services allow you to change your DND preferences. That means you can unblock some categories from the DND portal zone, like for instance, messages from banks can be unblocked while other numbers remain blocked.
- Despite registering for DND services, you can complain if you receive any unsolicited calls or messages.
- After you file a complaint about the issues you had to face with DND services, you can keep an update on the status of whether any action has been taken or not on the complaints.
