SIM card
When you register as a subscriber
with a service provider, 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. 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 Ericsson
% 86 Battery.
Save contact information on your SIM
card before removing it from another
phone; for example, contacts may be
saved in the phone memory.
If you enter the wrong PIN three times in
a row, PIN Blocked appears. To unblock
it, you need to enter your PUK (Personal
Unblocking Key)
