Preparing Your Phone for Use 5
You need to do the following to use your phone:
•insert the SIM card
•attach the battery to the phone
•charge the battery
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 Phone Book information, among other things.
SIM cards come in two sizes. One is the size of a credit card and the other is
smaller. Your phone uses the smaller card. Many credit card-sized SIM cards
have a perforated smaller card that you can take out easily. Before you can use
your phone, you must insert the SIM card as shown below.
Inserting and Removing the SIM Card
1. Remove the battery if
attached. Slide the SIM card
into the slot, under the silver
colored holders, with the
golden connectors facing
down and the cut corner to
the right.
2. Raise the edge of the SIM card
and slide it out.
The PIN
Most SIM cards are supplied with a security code, also known as PIN
(Personal Identity Number), which you need to access the network.
Every time you turn on your phone, you are asked to enter your PIN. You will
find your PIN in the information from your operator.
Some operators may have services that require a second PIN, your PIN2.
You should be careful with your PIN, since it is your protection against
unauthorized use of your subscription.

6 Preparing Your Phone for Use
If your PIN is entered incorrectly three times in a row, the SIM card is
blocked. If this happens, you can unlock it by using your PUK (Personal
Unblocking Key code), which you also get from your operator.
Your T28 WORLD comes with a lithium battery. The battery is not charged
when you buy your phone, but there may be enough power to switch the
phone on. We recommend that you charge the battery up to three hours before
you use the phone for the first time.
Attaching the Battery to Your Phone
When to Charge the Battery
The battery that comes with your phone can be charged whenever you wish
without affecting its performance. You can also charge the battery when the
phone is off.
Toremindyouthatyouwillsoonneedtochargethebatteryorreplaceitwith
a charged one:
•an alarm signal (a short beep) sounds and the message
Attention! Battery low
appears in the display
•the indicator light on top of the phone starts flashing red
If you have an Ericsson-approved battery, you can check the remaining talk
and standby times in the Status menu by sliding the volume key upwards or
downwards in standby mode. You can move downwards in the menu by
pressing d. The remaining standby and talk times depend on the type of
battery you use and your position in the network. Please note that these times
are approximate and you may have 20% less time than is shown in the display.
Note! The phone turns itself off when the battery can no longer power it
satisfactorily.
The Battery
•Place the battery on the back of the phone and push until you hear a click.

Charging the Battery
Note! The electrical plug may look different depending on the electrical outlet
in your country. Do not connect it to any other item than your Ericsson Travel
Charger CTR-10. It must not be disconnected from the charger when plugged
into the electrical outlet.
To indicate charging:
•the indicator on the top of the phone shows a steady red light (or green,
if the phone is switched on)
•the message
Charging only is shown in the display
•the battery meter in the display pulses continuously
Note! If you charge a new battery that is empty, or a battery that has not been
used for a long time, it may take a while until you get an indication of
charging in the display.
An Ericsson-approved battery is indicated by
Ericsson Optimized charging each
time you start charging the battery when the phone is switched on. For the best
charging, talk and standby times in the long run, we recommend that you use
only Ericsson-approved batteries with your phone.
Batteries that are not Ericsson-approved are charged slowly for safety reasons.
These are indicated by
Charging alien battery each time you start charging the
battery when the phone is switched on.
Tip! You can use the phone while the battery is being charged. However, this
lengthens the charging time.
3. Connect the charger to the phone
as shown. The flash symbol on the
plug must face upwards.
1. Make sure that the battery is
attached to the phone.
2. Connect the charger to the
electrical outlet.

Network Search
After you have turned on the phone (and entered your PIN), the phone
searches for a network.
When a network is found, the phone beeps three times. The indicator light on
top of the phone flashes green once every second and your network operator’s
name (in most cases abbreviated) appears in the display.
This is called standby mode. You can now make and receive calls.
Note! See “Error Messages” on page 104, if you do not reach standby.
The first time you turn on your phone, you may want to choose the ring signal
type and set the clock and date. For more information about these and other

20 T28 WORLD Features
T28 WORLD Features
Your T28 WORLD is a small new generation phone: a Dual Band
(GSM900/1900) phone with a lithium battery; a phone of modern design
and advanced technology.
The active flip makes it possible for you to answer by just opening the flip.
Or why not use the Voice Control and say ‘Answer’ to answer a call or ‘Busy’
ifyouwishtorejectthecall.Youcanalsocallapersonbysimplysaying
the name.
The T28 WORLD has a ‘Profile’ feature which makes it possible for you to
change a few settings by just choosing a certain Profile, since each profile
includes a group of settings preset to suit a certain environment. For example,
when you go to a meeting, you can just choose the ‘Meeting’ profile and a
number of settings that suit a meeting are then set automatically.
The Profiles are also related to intelligent accessories such as a desktop
charger, a portable or vehicle handsfree. For example, you may place the T28
WORLD in a vehicle handsfree kit and the ‘In Car’ profile is chosen
automatically.
In the display of the T28 WORLD you can see a mixture of text and symbols,
which makes it easier for you to move through the menus when you want to
change a certain setting, turn on the Vibrate Mode, send a message, save a
number and so on.
An extra feature is the numbered shortcuts, which takes you to a certain
setting quickly and easily. You may also create your own favorite menu,
‘My Shortcuts’, by including the settings you use most often. If you should
need help using the menus, the T28 WORLD is equipped with help texts to
guide you.
