About this user’s guide
For ease of reference, the “Getting to know your phone”
chapter gives a quick overview of the main functions of
the phone, shortcuts and general information.
More information and downloads are available at

or wap.SonyEricsson.com.
Note: Throughout this manual, WAP and Web are
used interchangeably to refer to internet services.
Available services
Some services and functions described in this user’s
guide are network- or subscription-dependent. Because
of this, some menus may not be available in your phone.
This symbol indicates that a service or function
is network or subscription-dependent.
Please consult your network operator for
more information about your subscription.
The 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 your phone number, the services included in
your subscription, and your phonebook information.
Tip: Check if your information is saved to the SIM card
before you remove it from another phone. For example,
phonebook entries may be saved in the phone memory.
For instructions on copying your SIM card information to
your phone, see “Phonebook” on page 26.
Assembly
Before you can use your phone you need to:
• Insert the SIM card.
• Attach and charge the battery. See “SIM card and
battery information” on page 4.
Note: Always turn off the phone and detach the
charger before you insert or remove a SIM card.

SIM card and battery information
It may take up to 30 minutes before an
icon appears when charging if the battery
is completely discharged.
1. Insert the SIM card. Make sure the SIM card is placed
under the metal clips.
2. Place the battery on the back of the phone with the
connectors facing each other (label side up).
3. Place the back cover into the bottom of the phone
and slide it up until it clicks into place.
4. Connect the charger to the phone at the lightning bolt
symbol. The lightning bolt symbol on the charger plug
must face upwards.
5. It may take up to 30 minutes before the battery charging
icon appears in the display. Wait approximately 4 hours
or until the icon indicates that the battery is fully charged.
If you do not see the battery icon after this time, press
any key or the center select key to activate the display.
The display will “sleep” during charging.
6. Remove the charger by tilting the plug upwards.

Holding the Phone
Hold your mobile phone
as you would any other
telephone.
Internal Antenna
Your phone is equipped
with an internal antenna.
For best reception, try to hold your phone so your hand
does not cover the internal antenna.The antenna is located
on the back of the phone under the Sony Ericsson logo.
Turning On the Phone
Press and hold NO until you hear
a tone. Enter your Personal Identity
Number (PIN), if you have one for
your SIM card. Your PIN is provided
by your network operator.
If you make a mistake while entering
your PIN, delete the wrong number
by pressing .
If your PIN starts with the same
digits as an emergency number, for
example 911, the digits are not hidden with an * when
you enter them. This is so that you can see and call an
emergency number without entering a PIN. See
“Emergency calls” on page 24 for more information.
Note: 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
(P ersonal Unblocking Key). Your PUK is provided by
your network operator.
Helpful Hints
When you power on your phone, you have
the option of viewing Helpful Hints. If you
select View Now, you will see a short demonstration of
how some of the keys work. You can choose to view
Helpful Hints later or you can select to not view them.
To select to not view them, scroll to NeverAskAgain
using your navigation key and press YES.
You can always access Helpful Hints by pressing
from the standby screen (as long as they have not been
deleted).
