Connectivity
Your phone supports different
methods for transmitting data in the
mobile network:
• The fastest method is UMTS (Uni-
versal Mobile Telecommunications
S ystem). If you use UMTS, you can
make video calls in high quality.
You can be connected to the Inter-
net permanently. Only the current
transmission time is charged by
the network operator. Some serv-
ice providers do not yet support
this service.
• GPRS (General Packet Radio Serv-
ice) is another method for trans-
mitting data in the mobile
network. With GPRS you can be
connected to the Internet perma-
nently, as well, if the network has
sufficient capacity. Only the cur-
rent transmission time is charged
by the network operator.
• GSM (Global System for Mobile
Communications) is a fully digital
standard for mobile networks
mainly used for voice calls and
text messages (SMS).
Depending on the surrounding net-
work and your provider, the differ-
ent methods are used automatically.
Depending on your provider you
may set which method to use
(page 125).
