In the fast-paced Indian digital market, businesses need instant communication that works without internet dependencies.

In 2025, data showed that over 9 billion SMS were sent daily in India alone, proving that text messaging is unmatched for immediate reach. Arihant Global empowers your business to send bulk sms online in minutes. Whether you use our robust web panel, scalable developer APIs, Excel sheets, or email triggers, our carrier-grade infrastructure ensures fast delivery at the lowest latency.

What is Bulk SMS & How Does It Work?

Bulk SMS is the automated broadcasting of large volumes of text messages to thousands of mobile subscribers simultaneously. Unlike a manual mobile text, an enterprise bulk SMS utilizes a sophisticated SMS Gateway connected directly to tier-1 telecom operators. When you trigger a campaign from Arihant Global, our intelligent routing system evaluates the fastest, least congested telecom path to deliver your message instantly.

Why is DLT Registration Mandatory?

lock

In India, the Telecom Regulatory Authority of India (TRAI) governs this ecosystem strictly through the Distributed Ledger Technology (DLT) system based on blockchain. DLT registration is legally mandatory for all Indian enterprises to eliminate spam and protect consumer data.

Before you send bulk sms, you must register your business entity, your headers (Sender IDs), and your message templates on a telecom DLT portal. This architecture ensures absolute transparency, high delivery success, and complete regulatory compliance.

Businesses sending SMS in India must:

  • Complete DLT registration
  • Register sender IDs
  • Register message templates
  • Obtain customer consent where applicable
