Getting Started
To remove the SIM card
Press the edge of the SIM card to release it from
the slot.
PIN
You may need a PIN (Personal Identity Number)
to activate the services in your phone. The PIN
is associated with your SIM card, and not with
the phone. Your PIN is provided by your service
provider. When you enter your PIN, each digit
appears as *, unless your PIN starts with the same
digits as an emergency number, for example 112.
The reason for this is to always let you make
emergency calls without entering a PIN.
If you make a mistake while entering your PIN,
delete the number by pressing .
Battery
Some functions use more battery power than others
and may cause a need for more frequent recharging.
If talk time or standby time becomes noticeably
shorter, you may have to replace the battery.
Only use approved batteries from Sony Ericsson

Turning on the Phone
and
Making Calls
Make sure that the phone is charged and your
SIM card is inserted before you turn it on.
When you have turned the phone on, you can use
the setup wizard to quickly and easily prepare
your phone for use.
If you enter the wrong PIN three times in a row, the SIM
card is blocked and the message PIN blocked appears.
To unblock it, you need to enter your PUK (Personal
Unblocking Key)
