Abstract
Techniques in a mobile equipment (ME) for use in performing an initialization procedure with a subscriber identity module (SIM) having a SIM Application Toolkit are described. The ME sends to the SIM a version of a terminal profile which indicates facilities of the SIM Application Toolkit that are supported by the ME. When the ME detects an error in response to sending the version of the terminal profile, the ME sends to the SIM a previous version of the terminal profile which indicates facilities of the SIM Application Toolkit that are supported by the ME. When the ME fails to detect the error in response to sending the version of the terminal profile, the ME completes the initialization procedure and performs steady-state processing using the SIM.
