Important! The plug-in SIM card information and its contacts
can be easily damaged by scratching or bending, so
be careful when handling, inserting, or removing the
card. Keep all SIM cards out of reach of small
children.
Carefully slide the SIM card into the SIM card socket (as
shown) until the card locks into place.
• Make sure that the card’s gold contacts face into the phone
and that the upper-left angled corner of the card is positioned
as shown.
Note: If the card is not inserted correctly, the phone will not
detect the SIM card. Re-orient the card back into the slot
if the SIM is not detected.
Installing the Battery
