OTP SMS in Cuddalore — FAQs

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 Cuddalore team can verify our 98-99% transactional delivery claim against your own traffic, every day.

How fast do OTPs reach users in Cuddalore?

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 Cuddalore numbers.

What happens if an OTP fails to deliver?

The platform retries over an alternate operator route automatically, and you can enable voice-OTP fallback where the code is read out by an automated call. Between retry logic and fallback, genuine non-delivery to Cuddalore users becomes vanishingly rare.

How long does OTP API integration take for a Cuddalore business?

About 15 minutes to first test code using our REST API and sample scripts; a production integration with delivery webhooks is usually same-day work. Our engineers assist your Cuddalore team directly during integration at no extra cost.

Is DLT registration needed for OTP messages in Cuddalore?

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 Cuddalore 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 Cuddalore campaign never delays a login code. Reporting stays unified in one dashboard.
