What is SMPP, and why do high-volume senders use it?
SMPP (Short Message Peer-to-Peer) is the standard protocol that telecom networks and SMS platforms use to exchange messages. Instead of making a separate web request for every SMS, your software opens a connection, called a bind, and keeps it open to send and receive messages continuously.
That makes SMPP the fastest way to send large volumes of SMS, which is why banks, fintech apps, SMS aggregators and resellers prefer it. As an SMPP provider in India, Bulk SMS India connects your bind to our platform, which carries the traffic over our direct links with India's mobile operators.

Frequently asked questions
What is an SMPP provider?
An SMPP provider gives businesses a direct connection to its SMS platform using SMPP (Short Message Peer-to-Peer), the standard protocol telecom networks use to exchange SMS. Instead of sending one HTTP request per message, your software keeps a live connection (a bind) open and sends large volumes quickly.
Is Bulk SMS India an SMPP provider?
Yes. Bulk SMS India is a CPaaS provider and SMS aggregator that offers SMPP connectivity to enterprises, aggregators and resellers, with direct agreements and connectivity with Airtel, Vodafone Idea (Vi), BSNL and Jio.
Who should use SMPP instead of an HTTP API?
SMPP suits businesses that send large or continuous volumes, such as banks, fintech apps, large e-commerce brands, aggregators and resellers with their own SMS software. For websites and apps with moderate volumes, our HTTP SMS API is simpler.
Do I need DLT registration for SMPP?
Yes. Every commercial SMS in India must follow TRAI DLT rules. Your entity, headers and templates must be registered, and the entity ID and template ID are passed with each message. We help you complete the process.
Can I get separate SMPP binds for OTP and promotional SMS?
Yes. We set up separate binds for OTP, service and promotional traffic, so OTPs travel on priority routes and are not delayed by bulk campaigns.
Do you provide delivery reports over SMPP?
Yes. Delivery receipts are sent back on your bind in real time, and you can also see per-message reports in our web panel.
Which SMPP client software can I use?
Any software that supports the standard SMPP protocol can connect, including popular open-source gateways and custom SMPP clients built by your team.
Do you offer SMPP to international customers?
Yes. We work with clients in India and international markets, including businesses abroad that send SMS to Indian numbers. Talk to our team about your routes and volumes.
