■ 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). Note that when you use
the phone without a SIM card, some functions appear dimmed in the menus and cannot be
used. Synchronizing with a remote internet server is not possible without a SIM card.
For an emergency call, some networks may require that a valid SIM card is properly inserted
in the device.
