Question: When a User Equipment (UE) receives a proactive SEND SS command and the UICC responds with '93 00' to the ENVELOPE (CALL CONTROL) command, how should the UE's Mobile Equipment (ME) proceed?
Option 1: Immediately send the supplementary service with the information as sent to the UICC.
Option 2: Set up a call using default settings since the UICC did not provide specific data.
Option 3: Not send the supplementary service or USSD operation at this time, but may retry the command.
Option 4: Ignore the UICC's response and proceed with the supplementary service as initially requested.
Explanation: When the UICC responds with '93 00' to the ENVELOPE (CALL CONTROL) command, it indicates that the ME should not send the supplementary service or USSD operation at that moment but may retry the command. This response suggests a temporary condition or a need for the ME to wait before proceeding, hence requiring a potential retry rather than an immediate action like sending the service or setting up a call without UICC's updated approval.
