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 items such as your
phone number, the services included
in your subscription, and names and
numbers in your contacts.
PIN
You may need a PIN (Personal Identity
Number) for your SIM card to start
your phone and activate services.
When you enter your PIN, each digit
appears as *, unless it starts with the
same digits as an emergency number,
for example 112 or 911. This allows for
emergency calls without entering a
PIN. Press
to correct mistakes.
Battery
Some functions use more battery
power than others and may cause a
need for more frequent re-charging. If
talk time or standby time becomes
noticeably shorter, you may have to
replace the battery. Only use
approved batteries from Sony

Save contact information on your SIM
card before removing it from another
phone.
