Assembly
Before you start using your phone, 
you need to insert a SIM card and the 
battery.
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.
Save contact information on your SIM 
card before removing it from another 
phone; for example, contacts may be 
saved in the phone memory.
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.
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) % 85 SIM card lock.
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 % 96 Battery.
