OTA

OTA or over-the-air attribute is an attribute of SMS-MT that forwards over-the-air configuration messages which include software updates, configuration settings, updates of encryption keys, and security locks. This type of SMS message is frequently used by Mobile Operators to provide or modify core network settings on your handset. These messages are used to optimize configuration settings e.g. SMS Service Center, Web settings, or to provide new services such as MMS.
