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.
Dual-tone multifrequency tones. Touch tones assign a
specific frequency, or tone, to each key so that it can easily
be identified by a microprocessor. Touch tones allow you to
communicate with voice mailboxes, computerized
telephony systems, and so on.
Extensible authentication protocol. EAP plug-ins are used in
wireless networks to authenticate wireless devices and
authentication servers.
Enhanced GPRS. EGPRS is similar to GPRS, but it enables faster
connection. For availability and data transfer speed, contact
your service provider.
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.
