Is DLT registration needed for OTP messages in Vellore?
Yes — OTP templates must be registered on DLT like all commercial SMS in India. The process is straightforward for transactional templates and we complete it with you free of charge; most Vellore businesses are approved within days.
Can OTP SMS work alongside my promotional campaigns?
Yes, on one account — but on separate routes. OTPs ride the dedicated transactional lane while promotions use marketing routes, so a big Vellore campaign never delays a login code. Reporting stays unified in one dashboard.
What does OTP SMS cost in Vellore?
Per-message transactional rates with volume slabs — no setup fee, no rental, free sandbox. OTP volumes grow fast, so slabs matter: share your monthly code estimate and we will quote exact Vellore pricing immediately.
Do OTPs deliver on DND numbers in Vellore?
Yes. OTPs are transactional messages, which TRAI permits to DND-registered numbers. Your Vellore users receive verification codes regardless of their DND status — one reason the transactional route and proper DLT templates matter.
Can I monitor my OTP delivery performance?
In real time. The dashboard shows sent, delivered, failed and average delivery time, sliceable by hour and operator — so your Vellore team can verify our 98-99% transactional delivery claim against your own traffic, every day.
How fast do OTPs reach users in Vellore?
Typically within a few seconds. OTP traffic uses a dedicated priority route across all Tamil Nadu operators with automatic re-routing on any slowdown. Delivery analytics in your dashboard show the exact timing of every code sent to Vellore numbers.
