A CPaaS provider and SMS aggregator, not a reseller
Bulk SMS India started in 2016 as a bulk SMS company in Yamuna Nagar, Haryana. Today we are a Communication Platform as a Service (CPaaS) provider working as an SMS aggregator: we run our own messaging platform, aggregate business traffic directly onto telecom operator networks and offer every major business channel from one account.
Businesses use us for OTPs, alerts and campaigns, and agencies use our white-label reseller program to offer SMS under their own brand. We serve more than 15,000 businesses across India and clients in international markets.
Our mission: to simplify business communication through reliable, scalable and cost-effective CPaaS solutions.

SMPP connectivity for enterprises, aggregators and resellers
As an SMPP provider, we give high-volume senders a direct SMPP connection to our platform, which carries traffic onward over our direct links with Airtel, Vi, BSNL and Jio. It suits banks, fintech apps, large e-commerce brands, other aggregators and resellers that send from their own SMS software.

Yes. Bulk SMS India has direct agreements and connectivity with India's mobile operators: Airtel, Vodafone Idea (Vi), BSNL and Jio. We also work with messaging partners such as SmartPing (Satzilio Telecom), Meta for WhatsApp and Google for RCS.
Is Bulk SMS India an SMS reseller?
No. Bulk SMS India is a CPaaS (Communication Platform as a Service) provider working as an SMS aggregator, with its own messaging platform, direct agreements and connectivity with Airtel, Vi, BSNL and Jio, and its own support team. We also run a white-label reseller program, so agencies can offer SMS under their own brand on our platform.
Is Bulk SMS India an SMPP provider?
Yes. We provide SMPP connectivity to enterprises, SMS aggregators and resellers that send high volumes from their own software, with separate binds for OTP, service and promotional traffic, delivery receipts over SMPP and DLT entity and template IDs passed with each message. The same routes are also available through our HTTP SMS API.
What is CPaaS?
CPaaS stands for Communication Platform as a Service. It is a cloud platform that lets businesses send SMS, WhatsApp, RCS, voice and email messages from one account, through a panel or APIs, without building their own telecom connections.
Can Bulk SMS India send SMS outside India?
Yes. We offer international SMS and work with clients in international markets as well as across India. Talk to our team about the countries and volumes you need.
Which channels does Bulk SMS India offer?
Bulk SMS (promotional, transactional and OTP), international SMS, WhatsApp Business API, RCS business messaging, voice calls, IVR, missed call services, email and AI-powered tools such as voice agents and chatbots.
How does intelligent routing help delivery?
OTPs, service alerts and promotional messages travel on separate routes, and traffic switches automatically to a backup route when one is busy or down. This keeps important messages fast even during heavy campaign traffic.
Does direct operator connectivity remove the need for DLT?
No. Every commercial SMS in India must still follow TRAI rules, including DLT registration of your entity, headers and templates. We help you complete DLT and check every message against it before sending.
