Sony Ericsson GC89 - Manual (Page 9)

Getting Started 9
Note:
Your network key is either 5 or 13 ASCII (text) characters, or 10 or 26 hexadecimal (0-9, A-F)
characters.
Network and Subscription
The network subscription you use in conjunction with your GC89 depends on the functions and
features your network operator can provide. Contact your network operator or service provider to
make sure the options you require are available. Make sure that data options are included in your
subscription, as these are usually optional services.
Note:
Mobile operators often provide a number of connectivity options via EDGE/GPRS such as
WAP and Internet. Verify the service you require, such as Internet, email or corporate VPN
(Virtual Private Network) service is available through your mobile operator and enabled on
your subscription.
The functionality of the different subscriptions available from networks operators are discussed
below:
Circuit Switched Data (CSD)
CSD is the original GSM network data transfer method, used in the past for WAP. Almost all GSM
networks have this capability at 9.6 kbps. It is possible for the network to upgrade the speed to
14.4 kbps. The GC89 operates at this higher speed where available.
General Packet Radio Service (GPRS)
GPRS is a type of network connection which provides “always on” mobility. The connection set up
is fast and, once connected, applications may send and receive data whenever required. In today’s
GPRS networks, the GC89 receives data at speeds up to 53.6 kbps and transmits at speeds up to
26.8 kbps.
Enhanced Data Rates for Global Evolution (EDGE)
EDGE enhances GPRS by increasing data throughput by a factor of 3. GPRS networks enhanced
with EDGE are often referred to as E-GPRS (Enhanced GPRS) networks. EDGE provides the
“always on” capability of GPRS but at faster speeds. EDGE technology is transparent, simply make
a GPRS connection as usual and benefit from the increase in speed where EDGE is available in a
network. When EDGE is available you can expect increased speeds of up to 200 kbps, dependent on
network coverage.
Short Message Service (SMS)
The PC can send and receive SMS text messages using the SMS Messages screen in the Wireless
Manager, see Wireless Manager SMS Messages Screen on page 70, for more details.
