7.7 SIM Personalisation
7.7.1 Introduction
SIM personalisation will limit the use of G600 to a single SIM, a SIM supplied by one Network/Sub-network/Service
Provider or a SIM purchased by a company (corporation). If a personalised G600 contains a SIM that is from a
different source it will display the message “SIM ERROR” when switched on. This personalisation of G600 is
sometimes referred to as SIM lock or SIM latch.
7.7.2 Testing
To test a personalised G600, when the user has not supplied the SIM, a SIM configured for test purposes (e.g. test
SIM or soft SIM) should be used. The mobile will recognise that the SIM is for testing purposes only and operate as
normal.
7.7.3 Personalisation Function
Personalisation is activated during manufacture and then enabled at a later stage. Enabling/disabling is available
by entering a special key sequence immediately after power on. Once the enable/disable menu is shown it is
possible to select the type of personalisation. When personalisation is enabled it is only possible to disable it if the
mobile contains an illegal SIM and the sixteen digit Control Key (CK) is known. When enabled the CK is withheld
from the user and cannot be read, for security reasons.
There are two special key sequences to enter the enable/disable menu:
