Bulk SMS India — Frequently Asked Questions
What is TRAI DLT registration and why is it required?
TRAI (Telecom Regulatory Authority of India) mandated DLT (Distributed Ledger Technology) registration for all commercial SMS senders since 2019. It is a blockchain-based system to reduce spam. Three levels are required: (1) Entity Registration — your business, (2) Header Registration — your sender ID, (3) Template Registration — every message template. Non-DLT-compliant SMS is blocked by all four Indian carriers. BulkSMSHub manages all three DLT levels as part of our service. Apply for DLT registration here.
What is the difference between promotional and transactional SMS in India?
Promotional SMS: marketing messages sent only to opted-in subscribers, blocked to DND-registered numbers, allowed 9 AM–9 PM IST only. Transactional SMS: service messages related to an existing customer relationship (bank alerts, delivery updates, booking confirmations), can be sent 24/7 and reach DND numbers. OTP SMS: highest-priority transactional subtype for one-time passwords, bypasses DND completely. BulkSMSHub automatically routes each message on the correct TRAI-compliant path.
How fast is OTP SMS delivery in India?
BulkSMSHub OTP SMS delivery in India via direct SS7: Jio 800–1,100ms, Airtel 850–1,100ms, Vi 900–1,200ms, BSNL 950–1,300ms. Overall India average: 900–1,100ms. This is significantly faster than grey routes averaging 3–5 seconds. For fintech, banking and e-commerce OTP where user experience depends on speed, direct carrier routing is essential.
