DNS Domain name service. An internet service that
translates domain names such as www.nokia.com into
IP addresses such as 192.100.124.195. Domain names
are easier to remember but this translation is needed
because the internet is based on IP addresses.
EAP Extensible authentication protocol. EAP plug-ins are
used in wireless networks to authenticate wireless
devices and authentication servers.
EGPRS Enhanced GPRS. EGPRS is similar to GPRS, but it enables
faster connection. For more information on the
availability of EGPRS and data transfer speed, contact
your service provider.
GPRS General packet radio service. GPRS enables wireless
access for mobile phones to data networks (network
service). GPRS uses packet data technology where
information is sent in short bursts of data over the
mobile network. The benefit of sending data in packets
is that the network is occupied only when sending or
receiving data. As GPRS uses the network efficiently, it
allows for quick data connection setup and fast data
transmission speeds.
You must subscribe to the GPRS service. For availability
and subscription to GPRS, contact your service
provider.
During a voice call, you cannot establish a GPRS
connection, and any existing GPRS connection is put on
hold unless the network supports dual transfer mode.
GPS Global positioning system. GPS is a worldwide radio
navigation system.
HSDPA High-speed downlink packet access. HSDPA brings
high-speed data delivery to 3G terminals, ensuring that
users requiring effective multimedia capabilities
benefit from data rates previously unavailable because
of limitations in the radio access network.
HTTP Hypertext transfer protocol. A document transfer
protocol used in the web.
HTTPS HTTP over a secure connection.
IMAP4 Internet mail access protocol, version 4. A protocol
used for accessing your remote mailbox.

WLAN using a WLAN access point.
PIN Personal identity number. The PIN code protects your
device from unauthorised use. The PIN code is supplied
with the SIM card. If the PIN code request is selected,
the code is required each time the device is switched
on. The PIN code must be 4 to 8 digits long.

directly from the web without downloading them first
to your device.
UMTS Universal mobile telecommunications system. UMTS is
a 3G mobile communication system. Besides voice and
data, UMTS enables audio and video delivery to
wireless devices.
When you use your device in GSM and UMTS networks,
multiple data connections can be active at the same
time, and access points can share a data connection. In
the UMTS network, data connections remain active
during voice calls. You can, for example, browse the
web faster than previously possible while
simultaneously speaking on the phone.
UPIN PIN code used in UMTS network.
UPUK UPIN Unblocking Key. UPUK code is required to change
a blocked UPIN code or PIN2 code. The length of the
code is 8 digits.
USIM SIM card used in UMTS network.
USSD command A service request, such as request to activate an
application or configure various settings remotely,
