FAQ

SMS — Questions Answered

What is DLT and why is it needed?
DLT (Distributed Ledger Technology) is TRAI's mandatory system for SMS in India. Every sender, template & Sender ID must be registered on the DLT portal. We handle the entire registration for you — free.
How fast is OTP delivery?
Average OTP delivery is 2–3 seconds across Airtel, Jio, Vi & BSNL. Direct carrier connections ensure no aggregator-hop delay.
Can I send promotional SMS on DND numbers?
No. Promotional SMS is blocked on DND numbers as per TRAI rules. However, transactional SMS (OTPs, order updates, alerts) bypasses DND — allowed 24/7.
What is a Sender ID?
A 6-character alphanumeric ID (like WAPIBX) that identifies your brand on every SMS. We register it under your DLT entity — usually within 24-48 hours.
Can I send bulk SMS to 1 lakh+ numbers?
Yes. Our carrier infrastructure supports 1 lakh+ SMS per hour. You can upload CSVs, sync from CRM, or segment by tags.
Do you offer real-time delivery reports?
Yes. Every SMS shows sent, delivered, failed & DND status — via dashboard & webhook. Failed SMS can auto-retry or fallback to WhatsApp.
Is the pricing per SMS or per campaign?
Pricing is per SMS, with volume-based discounts. Transactional SMS starts around ₹0.15–0.25 per SMS. Promotional SMS is slightly cheaper. Contact us for a custom quote.
Is there a free trial?
Yes. Book a demo and we set up a free trial with your own templates — including DLT registration support.
