Insert a SIM card and battery
This phone is intended for use with a BL-4U battery. Always use original Nokia batteries.
The SIM and its contacts can be easily damaged by scratches or bending, so be careful when handling, inserting, or removing the card.
Put your fingernail in the gap on the right edge of the phone, then carefully lift and remove the back cover (1).
If the battery is in the phone, lift it out (2).
Slide the SIM under the metal tab (3). Make sure the contact area of the card is face down and the tab holds the SIM in place (4).
Line up the battery contacts, push the battery in (5), then replace the back cover (6).
