TRAI fines for non-DLT or unregistered template SMS, on top of operator suspensions.
Mandatory since 2021

From KYC to first compliant send for a small business with documents ready.
The DLT pipeline
Five gates between you and a compliant first SMS.
Most teams confuse header with sender ID, or skip consent templates. We don't — and we don't let your DLT account either.

Template anatomy
A registered content template — and why every part matters.
Variables, category, and sender header are all immutable after approval. We get them right the first time.
Transactional
OTPs, password resets, payment receipts, banking alerts.
Service Implicit
Triggered by user action — order confirms, ticket alerts.
Service Explicit
Sent post-consent — appointment reminders, balance alerts.
Promotional
Offers, campaigns. Requires DND scrubbing and 10am-9pm window.
What we wire up
The flows we register and integrate, end-to-end.
We do not just register — we map approved templates into your codebase and verify a live send.
Order & ticket alerts
E-commerce, logistics, ticketing.
Appointment reminders
Healthcare, salons, fitness.
Account & banking
Statements, balance, KYC nudges.
Common questions
DLT, briefly demystified.
Do I need DLT if I send only OTPs?
Yes. All operator-bound SMS to Indian numbers — including OTPs — flow through DLT-registered headers and templates since the 2021 TRAI mandate.
Can the same header send to all operators?
Yes — once registered on one operator DLT portal, the header is replicated across operators in 24–72 hours. We track the rollout.
How long do template approvals take?
Header: usually 2–4 hours. Content templates: 2–12 hours depending on operator queues and content category.
Do you handle promotional templates too?
Yes. Promotional needs DND scrubbing, time-window enforcement, and stricter content review — we configure all of it.
