■ 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). Also reading and writing of service tags or payment
and ticketing with NFC may be possible without installing a SIM card.
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.
