All operators follow TRAI’s DLT framework, but businesses often choose operators based on ease of registration, portal usability, and support. We at GreenAds Global assist you in selecting the ideal operator suited to your business needs.

A sender ID (also known as Header ID or Centre ID) helps telecom operators and recipients identify the type of SMS being sent and ensures that messages are sent to the right category as per regulations.

There are three main types of sender IDs used in DLT registration:

• Promotional – For marketing and promotional messages
• Service (Inferred/Explicit) – For information-based messages to registered users
• Transactional – For OTPs, alerts, and essential service messages

‍

The registration fees for different operators are as follows:

• TATA – ₹5,000 + GST
• VI (Vodafone Idea) – ₹5,000 + GST
• Videocon – ₹5,000 + GST
• Jio – ₹5,000 + GST
• Airtel – ₹5,000 + GST
• BSNL – ₹3,000 + GST

We guide all our clients through this as part of our onboarding as a bulk SMS service provider.

‍

No, sending SMS without completing DLT registration is not permitted for promotional or transactional messages. As a trusted bulk SMS service provider, we help clients complete the DLT process smoothly to avoid any disruptions.

DLT registration is essential to reduce spam, ensure sender transparency, and comply with telecom regulations. It protects recipients from unsolicited messages and enhances the credibility of genuine bulk SMS campaigns.

DLT (Distributed Ledger Technology) registration is a mandatory process introduced by TRAI (Telecom Regulatory Authority of India) to regulate commercial SMS and prevent spam. All businesses using a bulk SMS service provider must register with DLT platforms to continue sending SMS campaigns.

You can get started with Bulk SMS in just a few steps:

1. Choose a reliable Bulk SMS provider (like GreenAds Global).
2. Sign up and complete DLT registration (mandatory in India).
3. Recharge your account based on your messaging volume.
4. Start sending messages via the web panel, mobile app, or API.

We provide a complete solution including DLT support, template setup, analytics, and campaign tools—making Bulk SMS easy for any business.
