Bulk SMS Solutions for Chennai Businesses

Nagar and some of India's leading hospitals. As a Bulk SMS Service Provider in Chennai, Fivo SMS supports all of them with one platform for SMS and WhatsApp.
Areas we serve: T. Nagar, Anna Nagar, Adyar, Mylapore, Nungambakkam, Egmore, Guindy, Velachery, OMR (Perungudi, Sholinganallur), Porur, Ambattur and Tambaram — and businesses across Tamil Nadu.

DLT-Compliant SMS Services
TRAI requires every business sending commercial SMS to be registered on a DLT platform. It is a one-time setup that applies across Jio, Airtel, Vi and BSNL. Here's what to expect at each stage.
| Stage | What happens | Typical time* |
|---|---|---|
| 1. Entity registration | Your business is registered as a Principal Entity using PAN and business proof | 1–3 working days |
| 2. Header (Sender ID) | Your brand name header is registered for each message type you need | 1–2 working days |
| 3. Templates | Your message formats are submitted and approved, with variables and links set correctly | 1–2 working days |
| 4. PE–TM binding | You authorise Fivo SMS as your telemarketer on the DLT portal | 1–2 working days |
| 5. Go live | Add credits and send from the panel or API | Same day |
*Timings vary by operator and depend on complete documents. Our team checks everything before submission to avoid delays. Read the DLT guide >>
Promotional and Transactional SMS
Reach New and Existing Customers
Offers, launches and invitations to non-DND numbers, sent between 10:00 AM and 9:00 PM.
- Pongal, Deepavali and wedding-season offers

How message length is counted
Each part is charged as one SMS — so a 200-character English message uses 2 credits. Service implicit and service explicit routes are also available for renewals, reminders and consent-based offers.
OTP SMS Services in Chennai
Chennai's product companies, hospitals, banks and dealer portals all depend on OTPs that arrive quickly. Fivo SMS sends them on priority transactional routes, 24×7, to every network including DND numbers — with delivery status for each code and voice OTP as a backup.
- Sign-up, login and two-factor authentication
- Patient and customer portal access

Short, branded and clear about expiry — with a reminder never to share the code. We help you register OTP templates like this so they are approved quickly.
