Bulk SMS Service in Bengaluru
What is a bulk SMS service for businesses in Bengaluru?
A bulk SMS service for Bengaluru companies delivers OTPs, onboarding messages and delivery alerts to users' phones through an API, on DLT-registered sender IDs. SaaS, D2C and logistics teams use it as the reliable channel for login codes and as a fallback when push notifications are missed.
Why SMS works for Bengaluru businesses
Bengaluru has many software products and delivery-led businesses, and most of them need an OTP or a status alert at the exact moment a user acts. A REST API with delivery webhooks lets engineers send the SMS and track the result without managing telecom connections themselves.
Users here read Kannada, English and often Hindi or Tamil. Because SMS needs no app, it also covers customers who have notifications switched off, which is why many apps keep SMS as the fallback behind push.

What you need before sending bulk SMS in Bengaluru
These steps are national, so they are the same in Bengaluru as anywhere in India.
Entity registration: register your business on TRAI's DLT platform. See DLT registration.
Sender ID and templates: register the header (sender ID) and each message template, including its variables, before you send.
The right message type: OTPs and account alerts are transactional; marketing is promotional and needs consent. See OTP SMS.
Consent and DND: promotional messages respect DND preferences and permitted hours. See DND compliance in India.
Send from the panel or through the SMS API, and track each message with delivery reports. Primary source: TRAI.
SMS templates in English, Kannada
Examples only. Words in braces are variables, and every template must be registered on DLT before use. Non-English SMS is sent as Unicode, which fits fewer characters per message part.
English: Delivery update
Hi {name}, your order {order_id} is out for delivery. Share OTP {otp} with the rider. - {brand}
In English: A delivery update carrying a handover OTP.
Kannada: OTP
ನಿಮ್ಮ OTP {otp} ಆಗಿದೆ. ಇದನ್ನು ಯಾರಿಗೂ ಹಂಚಿಕೊಳ್ಳಬೇಡಿ.
In English: Your OTP is {otp}. Do not share it with anyone.

Bulk SMS questions from Bengaluru businesses
How do Bengaluru developers send SMS from their app?
Through a REST API: call it with the number, the registered template ID and the variables, then read delivery status from a webhook. See the SMS API page for the request format.
Can I send Kannada SMS?
Yes. Register the Kannada template on DLT and send it as Unicode. Unicode messages hold fewer characters than English, so long messages are split into more parts.
How much does bulk SMS cost for a business in Bengaluru?
Price depends on the message type, route and monthly volume, not on the city. See SMS pricing for India or request a quote for your volume.
Is bulk SMS allowed for businesses in Bengaluru?
Yes, within TRAI's rules, which apply across India. Register your entity, sender ID and templates on DLT, send promotional messages only with consent and to numbers not on DND, and keep to permitted sending hours.
