Question: For Automatic Personalization of a Mobile Equipment (ME) using the first inserted IM (e.g., SIM/USIM), what is a prerequisite for successful SP (Service Provider) and Corporate personalization, assuming the ME manufacturer has enabled this feature?
Option 1: The ME must support dual-SIM functionality.
Option 2: The SIM/USIM must have default contents in GID1 and GID2 files.
Option 3: The IM (SIM/USIM) inserted must be from the same region as the ME's default settings.
Option 4: The SIM/USIM must support GID1 and GID2 with non-default contents.
Explanation: For SP and Corporate personalization to automatically occur when an IM (such as a SIM or USIM) is inserted into an ME that has been enabled for automatic personalization, the SIM/USIM must support specific identifiers (GID1 and GID2 as required) and these identifiers must contain non-default values. This ensures the ME can properly personalize based on the service provider's or corporation's predefined settings associated with those identifiers.
