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.
