In general, the term OTA implies the use of wireless mechanisms to send provisioning data or update packages for firmware or software updates to a mobile device - this is so that the user does not have to go to a store or a service center to have applications provisioned, paraméters changed or firmware or software updated. Non-OTA options for a user are a) to go to a store and seek help b) use a PC and a cable to connect to the device and change settings on a device, add software to device, etc.
