  • METHODS FOR PROVISIONING UNIVERSAL INTEGRATED CIRCUIT CARDS
    Publication number: 20150044995
    Abstract: A system is described that can perform a method for receiving a request to modify a universal integrated circuit card, generating a package comprising configuration data for modifying the universal integrated circuit card, instructing an over-the-air system to transmit the package encrypting the package with a transport key to generate an encrypted package, and transmitting the encrypted package to a communication device communicatively coupled to the universal integrated circuit card to provision the universal integrated circuit card. The system can also perform a method of providing a mobile network operator trusted service manager system information relating to the configuration data to enable the mobile network operator trusted service manager system to manage content and memory allocation of the universal integrated circuit card.
