OTP SMS in Gangtok — FAQs

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

What does OTP SMS cost in Gangtok?

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 Gangtok pricing immediately.

Do OTPs deliver on DND numbers in Gangtok?

Yes. OTPs are transactional messages, which TRAI permits to DND-registered numbers. Your Gangtok 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 Gangtok team can verify our 98-99% transactional delivery claim against your own traffic, every day.

How fast do OTPs reach users in Gangtok?

Typically within a few seconds. OTP traffic uses a dedicated priority route across all Sikkim operators with automatic re-routing on any slowdown. Delivery analytics in your dashboard show the exact timing of every code sent to Gangtok 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 Gangtok users becomes vanishingly rare.
