Why Businesses in Thiruvananthapuram Choose Techto Networks for Bulk SMS

Thiruvananthapuram (Trivandrum) is Kerala's most dynamic business city — home to the Technopark IT campus, a thriving healthcare and education sector, and a rapidly growing retail economy.

Our servers are directly connected to TRAI-authorised telecom routes, which means every message you send reaches your customer without delay, regardless of their network — Airtel, Jio, BSNL, or Vodafone Idea.

Types of Bulk SMS Services We Offer in Thiruvananthapuram

Promotional SMS in Thiruvananthapuram

Promotional SMS is designed to broadcast your offers, discounts, product launches, and event announcements to a wide audience. Our promotional SMS service in Thiruvananthapuram lets you target both DND and non-DND numbers during permitted hours (9 AM to 9 PM as per TRAI guidelines).

Ideal for: Retail stores in East Fort & Chalai market, restaurants running happy-hour deals, real estate developers announcing new projects in Kazhakkoottam, and event organisers promoting concerts or expos across the city.

Transactional SMS in Thiruvananthapuram

Transactional SMS is used for time-critical messages like order confirmations, appointment reminders, bank alerts, and delivery notifications. Unlike promotional SMS, transactional messages are delivered 24/7 — including to DND-registered numbers — because they carry information the customer has actively requested.

Ideal for: Hospitals and clinics sending appointment confirmations, e-commerce brands sharing order updates, schools and colleges notifying parents, and financial services companies sending account alerts.

• No DND filter — reaches every number on your list

OTP SMS Service in Kerala

OTP (One-Time Password) SMS is mission-critical. A slow or failed OTP means a lost transaction. Our OTP SMS gateway in Kerala uses a dedicated high-priority route that bypasses congestion and delivers authentication codes in under 3 seconds — even during peak traffic.

Ideal for: Fintech apps, online payment portals, healthcare platforms, login verifications, and any digital service requiring two-factor authentication (2FA).
