Get started

Before you start using your phone, remove the
back cover to insert the micro-SIM cards (also
known as mini-UICC cards).

Remove the back cover

Make sure the phone is switched off.

1. At the top corner of the phone, put your index
finger in the seam between the screen frame and
the back cover. Do not use any sharp tools, as
they may damage the phone.

2. Press the middle of the back cover, bend the
cover open, and remove it.

3

Insert the SIM and memory card

1. If the battery is in, lift it out.

2. Slide the micro-SIM card into the SIM slot with

the metal contact area down.

3. If you have a second SIM card, push it into the
SIM2 slot, until it locks into place (RM-978).

4. If you have a memory card, slide the card into
the memory card slot.

Use of incompatible SIM cards, or use of SIM card
adapters, may damage the card or the device, and
may corrupt data stored on the card.

Replace the battery and back cover

1. Line up the battery contacts, and put the

battery in.

2. Press the bottom edge of the back cover
against the bottom edge of your phone, and snap
the cover into place.

3. To switch your phone on, press and hold the
power key.

Charge the battery

Plug a compatible charger into a wall outlet, and
connect the micro-USB end to your phone. For
best performance, authentic Nokia USB chargers
are recommended. You can also charge your
phone from a computer with a USB cable.

If the battery is completely discharged, it may
need to charge for up to 20 minutes before you
can use your phone. The charging indicator may
not be displayed in this time.
