OTA

A feature of SMS-MT that sends over-the-air configuration messages, such as software updates, configuration settings and security locks.

As mobile phones accumulate new applications and become more advanced, OTA configuration has become increasingly important as new updates and services come on stream. OTA via Short Message Service (SMS) optimises the configuration data updates in subscriber identity module (SIM) cards and handsets, and enables the distribution of new software updates to mobile phones or provisioning handsets with the necessary settings with which to access services such as WAP or MMS. OTA messaging provides remote control of mobile phones for service and subscription activation, personalization, and programming of a new service for mobile operators and telco third parties.
