Question: In a Universal Subscriber Identity Module (USIM) Application Toolkit (USAT), when sending an `ENVELOPE` command from the Mobile Equipment (ME) to the UICC for an EVENT DOWNLOAD related to Closed Access Group (CAG) Cell Selection, what is the condition under which the 'Access Technology' data object is not included in the command parameters?
Option 1: When the device is camping on a cell without CAG.
Option 2: When the previous event indicated the UE was not camped on a CAG cell.
Option 3: If the device is not camping on any cell.
Option 4: When the CAG cell selection status indicates successful selection.
Explanation: According to specifications, the 'Access Technology' data object is only included if the device is camping on a cell. If the device is not camping on any cell, this specific data object shall not be present in the command parameters, ensuring that unnecessary information is not transmitted when the device lacks a serving cell connection.
