Question: During the Personalisation cycle of a Mobile Equipment (ME), what is the prerequisite for initiating the personalisation process, in terms of the Service Provider (SP) personalisation indicator setting?
Option 1: The SP personalisation indicator must be set to 'on' to ensure previous settings are acknowledged.
Option 2: The SP personalisation indicator must be set to 'off', indicating the ME is currently unpersonalised.
Option 3: The SP personalisation indicator setting is irrelevant to initiating the process.
Option 4: The SP personalisation indicator must toggle from its current state to initiate the process.
Explanation: For the personalisation process of a Mobile Equipment (ME) to commence, it must be in an unpersonalised state. This is ensured by requiring the Service Provider (SP) personalisation indicator to be set to 'off'. This setting guarantees that any existing personalisation settings are cleared or non-existent, allowing for a new personalisation cycle to begin without conflicts or overlaps.
