Frequently Asked Questions (FAQ)

What is DLT registration and is it mandatory in India?

Yes, DLT (Distributed Ledger Technology) registration is mandatory for any business sending commercial SMS in India. It's a blockchain-based system mandated by TRAI to curb unsolicited messages and spam. You must register your business (as a Principal Entity) and get your Sender IDs (Headers) and message templates approved on a DLT platform.

How is bulk SMS pricing calculated in India?

Pricing is typically calculated on a per-SMS basis. The cost per SMS decreases as the volume of your purchase increases. Most providers sell SMS credits in packages, and one credit usually equals one standard SMS of 160 characters.

Can I send bulk SMS to DND numbers?

You can only send transactional SMS (like OTPs, order confirmations, and informational alerts) to numbers registered on the Do Not Disturb (DND) list, and only through approved templates and Sender IDs. Sending promotional SMS to DND numbers is strictly prohibited and can result in heavy penalties.
