6 Preparing Your Phone for Use
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 subscrip-
tion, 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.
