A bulk SMS service provider in Bangalore for product teams
Bangalore's startups, SaaS companies, fintechs and quick commerce apps mostly use SMS for one thing: getting a code or an alert to a user within seconds. Marketing usually comes later. What matters is a clean API, predictable latency, honest delivery reports and someone who answers when OTPs stop going through.
Our platform gives you HTTP, REST and XML APIs, DLR webhooks, scheduling and sub-accounts. AvanceZone has been in bulk SMS since 2000 and runs direct connectivity to Jio, Airtel, Vi and BSNL with 6+ redundant routes, targeting 99.9% platform uptime.
OTP and transactional SMS done right
For non-bank businesses, OTPs are registered as service templates and show the -S suffix after your header. Banks and regulated lenders register OTPs as transactional and show -T. Either way, an approved template can be sent at any hour, including to DND numbers.
Keep OTP templates short and in English plain text so they fit in one 160-character part. Each {#var#} holds up to 30 characters, enough for a code, an app name or an amount.
- Login and signup OTPs with a validity window
- Payment, refund and wallet credit alerts
- Order placed, packed, out for delivery and delivered updates
- Password reset and new device login warnings
Choosing between SMS, WhatsApp and RCS for OTP
SMS OTP on our Business plan costs ₹0.15 per delivered message plus GST and works on every phone with no app. WhatsApp authentication messages cost ₹0.12 to ₹0.16 depending on plan, plus a monthly plan fee, and need the user to have WhatsApp. Jio's RCS OTP pricing announced in September 2026 sits at ₹0.11 to ₹0.16, but reach depends on handset support.
Many Bangalore teams use SMS as the default and add WhatsApp or RCS as a second channel. Our account lets you run all three, so fallback logic stays in one place.
Kannada SMS and festival sale days
If your users are outside the IT corridors or across Karnataka, Kannada messages often get better attention. Kannada goes as Unicode with 70 characters per part. A delivery update like "ನಿಮ್ಮ ಆರ್ಡರ್ ಇಂದು ತಲುಪಲಿದೆ" fits easily in one part.
Plan for traffic peaks around Ugadi, Ganesh Chaturthi, Dussehra and Diwali sales. Register promotional templates two weeks ahead, use only whitelisted links (public URL shorteners are blocked), and keep campaign SMS within 10am to 9pm. OTP traffic on sale days can be several times normal, so load test early with us.
Support from Coimbatore, pricing and onboarding
We do not have a Bangalore office. Our engineering and support team works from Sulur, Coimbatore and helps Bangalore customers on phone, WhatsApp, email and screen share during sales hours. Developers can reach the same people who run the routes, which shortens debugging. Enterprise customers get a dedicated account manager, 24/7 phone support and an SLA.
Starter is ₹0.20 per SMS for up to 10,000 a month, Business ₹0.15 for up to 1,00,000, and Enterprise is custom with volume discounts. There is no monthly platform fee. DLT registration help is free of service charge; operator fees are paid separately.

Frequently asked questions
Do you provide an OTP SMS API for Bangalore startups?
Yes. You get HTTP, REST and XML APIs with JSON responses, delivery report webhooks and sub-accounts. OTPs travel over direct operator routes and are typically delivered in a few seconds. The platform supports up to about 10,000 SMS per second, which covers most sale-day and launch spikes.
Is there a Bangalore office or local support team?
No. Our only office is in Sulur, Coimbatore. Bangalore customers are supported remotely by phone and WhatsApp on +91 95851 60363, by email and over screen share, Monday to Saturday from 9am to 7pm. The platform itself runs 24x7, and Enterprise plans include 24/7 phone support.
Should my OTP template be service or transactional?
If you are a bank, register OTPs as transactional, and users will see a -T suffix after your header. Most other businesses, including startups and fintech apps that are not banks, register OTPs as service implicit templates with a -S suffix. Both can be sent at any hour, including to DND numbers.
How much does OTP SMS cost compared with WhatsApp?
SMS on our Business plan is ₹0.15 per delivered SMS plus GST, with no monthly fee. WhatsApp authentication messages cost ₹0.12 to ₹0.16 each, plus a monthly plan fee and one-time setup. SMS reaches every phone, while WhatsApp needs the user to have the app installed and active.
Can I send OTPs in Kannada?
You can, but most teams keep OTPs in English because a plain-text OTP fits in one 160-character part. Kannada uses Unicode with 70 characters per part, so it suits short delivery updates and greetings better. Register each language as its own DLT template.
Can I use separate sender IDs for different apps?
Yes. Create a sub-account for each app or brand, each with its own API keys, sender IDs and reports. Each header must be registered on DLT and costs about ₹590 per year in operator fees. Billing can stay on one parent account.
