Binary SMS

Binary SMS are messages that do not contain text information, but encoded data in binary format. These messages are not displayed on the phone screen like regular text SMS, but are used to send special commands or files such as multimedia messages (MMS), settings updates, mobile device configurations, WAP push notifications and other service data.

What are binary SMS used for?

Binary SMS are used in a variety of scenarios involving the transmission of encoded data and configurations. Here are the main areas of their application:

Mobile device settings. Mobile operators send binary SMS to automatically configure devices. This includes sending Internet parameters (APN), MMS, WAP and other network settings so that the user's device can work correctly on the operator's network.
Multimedia Messaging (MMS). Binary SMS are used to transfer multimedia files such as images, ringtones and videos. These messages allow you to send data that cannot be sent as a plain text SMS.
WAP Push Notifications. Binary SMS is used to send WAP push notifications that contain links to web pages or mobile applications. These notifications are used for marketing campaigns or to provide access to content.
IoT device management. In the Internet of Things (IoT) industry, binary SMS is used to remotely manage and update device firmware. This allows operators and users to manage devices and perform updates without physically accessing them.
Mobile security. Binary SMS can be used to send commands to lock or delete data on lost or stolen devices. Such messages help ensure data security on mobile devices.
SIM activation. In some cases, binary SMS are used to activate SIM cards or update their settings at the service provider level.

These messages provide automatic execution of various functions on devices without the need for user intervention, which makes them an important tool in telecom and IoT systems.
