General Information
Operators & Subscription
To be able to use your phone, you need to have a sub-
scription to a network. This is obtained from the net-
work operator.
The services included in your subscription depend on
your choice of operator and/or subscription. Therefore,
some of the services and functions described in this
manual may not be accessible to you. If you want a
complete list of the services included in your subscrip-
tion, please contact your network operator.
GSM 900/1900 Dual Band
The Ericsson I 888 WORLD is a dual band phone, which
means that you can use your phone in two different
kinds of networks – the GSM 900 and the GSM 1900
systems.
The GSM 1900 system is used in the US and other parts
of the Americas, and the GSM 900 system is used in
Europe, the Asia/Pacific region and in some parts of
Africa. This means that you can use your I 888 WORLD
on six continents.
Consequently, the I 888 WORLD offers you enhanced
international roaming, thanks to the additional net-
works now available when you are out travelling.
The switching between the two systems is done auto-
matically, which means that you can use your phone
without ever having to consider which system is being
used. This is taken care of by the networks. However,
you should note that the functions offered and the net-
work coverage differ depending on your choice of op-
erator and/or subscription.
SIM & PIN
You will obtain a SIM (Subscriber Identity Module) card
with your subscription. The SIM card contains a com-
puter chip that keeps track of your phone number, the
services you have ordered from your network operator
and your Phone Book information, among other things.
Your SIM card is supplied with a security code or PIN
(Personal Identity Number), which you need in order to
gain access to the network. Your PIN may also be re-
quired when you want to change settings in your
phone. Furthermore, some operators may have
ser-vices that require a second PIN, your PIN2. You will
find your PIN (and PIN2) in the information from your
operator.
Every time you turn on your phone, it prompts you to
enter your PIN. If the PIN is entered incorrectly three
times in a row, the SIM card will be blocked. If this hap-
pens you can unlock it by using your PUK (Personal Un-
blocking Key code), which you also get from your op-
erator.
You should be careful with your PIN, since it is your pro-
tection against unauthorized use of your phone and
subscription.
