What is SMPP, and how does it differ from other SMS APIs?

SMPP (Short Message Peer-to-Peer) is a protocol designed for high-speed, high-volume SMS transmission. Unlike standard HTTP APIs, SMPP maintains a persistent connection, enabling faster message delivery and higher throughput.

Who should consider using the SMPP API?

Businesses or service providers that send large volumes of SMS messages—such as telecom operators, aggregators, or enterprises running extensive marketing campaigns—will benefit most from SMPP’s efficiency.

Is SMPP integration complex?

SMPP is more technical than standard APIs, but we’ve made it as smooth as possible. Our detailed documentation walks you through each step, and our support team is here to help you set up and troubleshoot whenever you need it.

How secure is messages transmission through SMPP API?
