Networks

If it is not within range, you may
use another network, provided your
network operator has an agreement
that allows you to do so. This is called
roaming.

can add a network to your preferred
networks. You can also change the
order in which networks are selected
during an automatic search.
Your phone also switches automatically
between GSM and 3G (UMTS) networks
depending on availability. Some
network operators allow you to switch
networks manually, since searching
for unavailable networks consumes
battery power.
