Tech — SMS & Voice

The channel that works when data does not.

SMS is unfashionable and undefeated. It reaches every handset, needs no app, no data connection, and gets read within minutes.

The problem

Why this usually goes wrong.

Most SMS problems in India are compliance problems. Templates are not registered, headers are wrong, and messages silently fail delivery while the dashboard reports success.

We handle DLT registration properly, monitor genuine delivery rather than submission, and separate transactional from promotional traffic so critical messages always land.

Questions

Answered before you ask.

What is DLT and do we need it?
DLT is the TRAI-mandated registry for commercial SMS in India. Without registered headers and templates, your messages will not be delivered. Registration is compulsory, and we handle it.
Why do our OTPs get delayed?
Almost always route quality or traffic mixed with promotional messages. Transactional traffic should sit on a dedicated high-priority route.
Can we send promotional SMS at any time?
No. Promotional messages are restricted to specific hours and only to numbers not on DND, unless you have documented consent.
Do you offer voice OTP as a fallback?
Yes, and it materially improves delivery for users in poor-coverage areas.
