Warning: With the flight profile you cannot make or receive any calls,
including emergency calls, or use other features that require network
coverage. To make calls, you must first activate the phone function by
changing profiles. If the device has been locked, enter the lock code. If you
need to make an emergency call while the device is locked and in the flight
profile, you may be also able to enter an official emergency number
programmed in your device in the lock code field and select 'Call'. The device
will confirm that you are about to exit flight profile to start an emergency call.
To deactivate the flight mode, select any other profile.
Note: In the flight profile, you may need to unlock the device and change to the
calling profile before making a call.

Functions without a SIM card

Several functions of your phone may be used without installing a SIM card (for
example, the data transfer with a compatible PC or another compatible device).
Without a SIM card, some functions appear dimmed in the menus and cannot be used.
For an emergency call, some networks may require that a valid SIM card is properly inserted
in the phone.
