Assembly
You need to do the following to use your phone:
• insert the SIM card
• attach the battery to the phone
• charge the battery
The SIM Card
When you register as a subscriber with a network operator, you get a SIM
(Subscriber Identity Module) card. The SIM card contains a computer chip
that keeps track of your phone number, the services included in your
subscription, and your Phone Book information, among other things.
SIM cards come in two sizes. One is the size of a credit card and the other is
smaller. Your phone uses the smaller card. Many credit card-sized SIM cards
have a perforated smaller card that you can take out easily. Before you can use
your phone, you must insert the SIM card as shown below.
Inserting and Removing the SIM Card
1. Remove the battery if attached. Slide the SIM card into the slot, under the
silvery holders, with the golden connectors facing down and the cut corner
to the right.
2. Raise the edge of the SIM card and slide it out.
The PIN
Most SIM cards are supplied with a security code, also known as PIN
(Personal Identity Number), which you need to access the network. Every
time you turn on your phone, you are asked to enter your PIN. You will find
your PIN in the information from your operator.
Some operators may have services that require a second PIN, your PIN2.
You should be careful with your PIN, since it is your protection against
unauthorized use of your subscription.
