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
www.SonyEricsson.com, www.SonyEricsson.com/fun
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.

This is the Internet version of the user's guide. © Print only for private use.

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
