OTA SMS (Over-the-Air SMS) is a special type of SMS message that allows carriers and other services to remotely change the settings of mobile devices. Unlike regular text messages, OTA SMS contains encoded commands and data that are automatically applied to the device.
This technology is used to automatically transmit configurations, updates and other settings without the need for physical access to the phone or manual customization by the user.
For example, telecom operators use OTA SMS to set Internet (APN) parameters, MMS, SIM card settings or change network configurations. This technology can also be used for software updates or device firmware upgrades.
The main advantage of OTA SMS is convenience and speed: the user does not need to enter settings himself, everything happens automatically, which simplifies the process of connecting to the operator's services and improves the user experience.
