Bulk SMS with DLT Registration — OTP, Alerts & Promotions

Bulk SMS still delivers what nothing else can: a message to any phone, instantly, with no app or internet needed, perfect for OTPs, transactional alerts and promotions. In India it requires DLT (Distributed Ledger Technology) registration for your entity, sender ID and templates, which we handle end to end so your traffic isn't silently blocked. We set up and manage OTP, transactional and promotional SMS, often alongside WhatsApp.

Why SMS still matters in a WhatsApp world

WhatsApp is powerful, but SMS does things WhatsApp can't. It reaches every phone with no app, no internet and no opt-in dependency, which is why it remains the backbone of OTPs and critical alerts. When a customer needs a one-time password to log in or pay, or a 'your order has shipped' alert, SMS delivers it instantly and universally. It's also the reliable fallback when a WhatsApp message doesn't land. For many businesses the right answer isn't WhatsApp or SMS, it's both, with SMS handling verification and essential transactional traffic and WhatsApp handling richer conversations.

The complication in India is DLT. Every business sender, sender ID and message template must be registered on the telecom DLT platform, or messages get silently blocked. It's a real compliance hurdle, and one we take off your plate entirely.

DLT registration, handled for you

DLT (Distributed Ledger Technology) registration is mandated by TRAI to stop spam, and it trips up most businesses trying to send SMS themselves. There are several moving parts: registering your business entity, getting your sender IDs (header) approved, registering each message template, and mapping templates to the right category, transactional, OTP, service or promotional. The rules also keep changing, including recent updates to message categories and mandatory sender-ID suffixes. We handle the full registration across operator portals and keep your setup current, so your SMS actually reaches phones instead of disappearing into a compliance black hole. You focus on the message; we handle the paperwork and the plumbing.

  • Entity, sender-ID (header) and template registration
  • Correct category mapping: OTP, transactional, service, promotional
  • Ongoing compliance as DLT rules and formats change
FAQ

Bulk SMS & DLT — FAQs

Is SMS still worth it when I have WhatsApp?

Yes. SMS reaches any phone with no app, internet or opt-in needed, which makes it essential for OTPs and critical alerts and a reliable fallback when WhatsApp doesn't land. Many businesses use both together.

What is DLT registration and do I need it?

DLT registration is mandatory in India for business SMS. Your entity, sender ID and every message template must be registered, or your messages are silently blocked. We handle the entire registration and keep it compliant.

Can you send OTP and transactional SMS?

Yes. We set up OTP, transactional alerts (orders, payments, appointments) and promotional campaigns, each registered under the correct DLT category so they deliver reliably and on time.
