There are up to six different access codes in your phone:
Security code (5 digits): The security code
protects your phone against unauthorized use and is supplied
with the phone. The pre-set code is 12345. Keep the code secret
and in a safe place separate from your phone.
PIN code (4 to 8 digits): The PIN (Personal Identification
Number) code protects your SIM card against unauthorized use.
The PIN code is usually supplied with the SIM card.
PIN2 code (4 to 8 digits): The PIN2 code may be supplied
with the SIM card and is required to access some functions,
such as charging unit counters.
PUK and PUK2 codes (8 digits): The PUK (Personal Unblocking
;Key) code is required to change a blocked PIN code. The PUK2
code is required to change a blocked PIN2 code.
Barring password: The barring password is needed when
using the Call barring service.

General Packet Radio Service. With GPRS you can be online all
the time. You can be continuously connected to data networks
and use your favorite information and entertainment services.
It also provides immediate connectivity and higher data throughput
than before, so information retrieval is more accessible and
convenient. The main initial use for GPRS is to have it as a
bearer for WAP services. In GPRS technology the data is sent
in 'packets;' this is well suited to the sporadic nature of
data applications. GPRS can also be used as a bearer for PC
applications in a similar way as CSD and HSCSD are used.
Global System for Mobile Communications, or GSM, is the digital
transmission technique widely adopted in Europe and supported
in North America for PCS. GSM uses 1900 MHz in the Americas,
and 900 MHz and 1800 MHz in Europe.
High Speed Circuit Switched Data. The most important feature
of this technology is the increased speed. This makes connection
times shorter and the use of current applications more convenient
and faster. Data connections can be up to four times faster
than earlier, which means that applications such as mobile navigation
services using maps and graphics become more attractive. As
HSCSD is 'circuit switched', it is more suited to applications
such as video conferencing and multimedia than applications
that send data in bursts such as e-mail. HSCSD allows wireless
data to be transmitted at 43.2 kilobits per second over GSM
networks. This is comparable to the transmission rates of usual
modems via fixed telephone networks today.

The infrared eye built into your Nokia 7250 can be used to transmit
data to another device with an infrared eye, without needing
to link the two with a cable. If you want to use your mobile
phone for sending computer data, to synchronize the contacts
in your phone, or to swap ringing tones with another infrared
user, it's a big plus.
Internet protocol address. A unique string of numbers that identifies
a computer on the Internet. Shown in groups separated by periods,
like this: 123.456.789.012.
ISDN connections are a way to establish a data call between
your phone and your access point. ISDN connections are digital
from end to end and as such offer quicker set-up times and faster
data rates than analog connections. In order to use ISDN, both
your Internet service provider and network operator must support
them.
Java™ is a programming language developed by Sun Microsystems.
Some versions of Java™ are likely to be used in the
creation of wireless services.
Liquid Crystal Display screens have low energy requirements
and are generally easy to read. LCD screens are made by sealing
a liquid compound between two pieces of glass and/or a filter.
The screen has hundreds or thousands of dots that are charged
or not charged, which makes them reflect or not reflect light
to form letters, characters and numbers. Some LCD screens
have
an electroluminescent panel behind them and are termed "backlit."
Refers to a type of battery, a Lithium-Ion battery, used to
power wireless communication devices. Li-Ion batteries are lighter
weight than earlier battery types, have a relatively long cycle
life and generally do not suffer from memory effect.

Using various products, services and technologies to transfer
messages from one person to another, or from one device to another
such as traditional numeric or alphanumeric paging, e-mail or
short messages (SMS) delivered to wireless devices.
Musical Instrument Digital Interface. A communications protocol
originally designed to allow synthesizers to communicate with
computers and each other.
Multimedia Messaging Service (MMS) is a new standard that is
being defined for use in advanced wireless terminals. The service
allows for non-real-time transmission of various kinds of multimedia
contents like images, audio, video clips, etc.
A term often used interchangeably with cellular phone or wireless
phone. Initially, a mobile phone referred to a phone attached
to a vehicle, the vehicle's battery and had an external antenna.
Mobile phones were distinguished from transportable, portable,
cordless and personal phones.
In the wireless industry, a network refers to the infrastructure
enabling the transmission of wireless signals. A network ties
things together and enables resource sharing.

Short Message Service is a feature available with some wireless
phones; it allows users to send and/or receive short alphanumeric
messages.
The length of time a wireless phone or communicator is fully
charged, turned on and ready to send and receive calls or data
transmissions. Standby time, once stated in only hours and minutes,
can now be extended to many days with current phone models.
Standby time is affected by the amount of time the phone is
used for talking because talking on a phone draws more energy
from a battery than standby time does. Wireless devices depend
on batteries for power; batteries slowly discharge their power
and must be recharged and eventually replaced.
Synchronization Application is a software
application that enables you to synchronize personal
information (contacts, to-do’s, and calendar entries) with a networked
server containing their personal information.
SyncML is a technology that enables different
kinds of devices and applications to synchronize data over
different kinds of networks. SyncML
is a communication protocol that defines the type of data
that can be synchronized, and how the devices communicate
between each other.

The length of time a wireless device may be engaged in transmission
(phone conversations, sending or receiving data) before it runs
out of battery power. Talk time, expressed in hours and minutes,
is much shorter than standby time because transmission requires
more power. Therefore, standby time is effected by the amount
of time the phone is used for talking. Wireless devices depend
on batteries for power; batteries slowly discharge their power
and must be recharged and eventually replaced.
Video Graphics Array. Supports pixel addressabilities of up
to 640 x 480 x 16. This is the de facto video standard and consists
of a number of video modes.
