Getting Started
Installing the SIM Card
When you subscribe to a cellular network, you are provided
with a plug-in SIM card loaded with your subscription
details, such as your PIN, any optional services available
and many others.
Important! The plug-in SIM card and its contacts can be
easily damaged by scratches or bending, so
be careful when handling, inserting or
removing the card.
Keep all SIM cards out of the reach of small
children.
1. If necessary, switch off the phone by holding down the
key until the power-off image displays.
2. Remove the battery. To do so:
1
Press and hold the battery lock above the battery
upward toward the top of the phone.
2
Lift the battery away, as shown.

the card face into the phone.
Note: When you need to remove the SIM card, slide it, as
shown, and take it out of the socket.

Getting Started
4. Place the battery so that the tabs on the end align with
the slots at the bottom of the phone.
5. Press the battery until it clicks into place. Make sure
that the battery is properly installed before switching
the phone on.
Charging a Battery
Your phone is powered by a rechargeable Li-ion battery. A
travel adapter comes with your phone for charging the
battery. Use only approved batteries and chargers. Ask
your local Samsung dealer for further details.
You can use the phone while the battery is charging, but
this causes the phone to charge more slowly.
