OTP SMS in Howrah — FAQs
What does OTP SMS cost in Howrah?
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 Howrah pricing immediately.
Do OTPs deliver on DND numbers in Howrah?
Yes. OTPs are transactional messages, which TRAI permits to DND-registered numbers. Your Howrah 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 Howrah team can verify our 98-99% transactional delivery claim against your own traffic, every day.
How fast do OTPs reach users in Howrah?
Typically within a few seconds. OTP traffic uses a dedicated priority route across all West Bengal operators with automatic re-routing on any slowdown. Delivery analytics in your dashboard show the exact timing of every code sent to Howrah 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 Howrah users becomes vanishingly rare.
How long does OTP API integration take for a Howrah 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 Howrah team directly during integration at no extra cost.
