How to send Binary SMS

In this guide, you will learn how to send a Binary SMS using the Ozeki SMS Gateway. Binary SMS messages are used to send raw data in hexadecimal format directly to mobile devices. This type of SMS is often used for technical tasks like device configuration, firmware updates, or delivering encoded information. It allows for silent, non-visible communication between systems, making it ideal for developers and system integrators. This tutorial will guide you through selecting the message type, entering the binary payload, and sending the message.

What is Binary SMS?

A Binary SMS is a type of message that delivers raw hexadecimal data to a mobile device. Unlike text messages, it sends binary content that is processed by applications, firmware, or system services. It’s commonly used for remote commands, firmware delivery, or application-level communication.

When is it best to send a binary SMS?

Binary SMS is best used when delivering low-level instructions or data between systems. This includes sending commands to IoT devices, triggering specific app behavior, updating configurations, or transferring data in non-human-readable formats. It's ideal for automation, system integration, and technical operations where direct device communication is needed without displaying content to the user.
