Nokia E5-00 - Manual (Page 76)

Network mode — Select which network to use. If you select Dual mode , the device
uses the GSM or 3G network automatically, according to the network parameters
and the roaming agreements between the wireless service providers. For details
and roaming costs, contact your network service provider. This option is shown only
if supported by the wireless service provider.
A roaming agreement is an agreement between two or more service providers to
enable the users of one service provider to use the services of other service
providers.
Operator selection — Select Automatic to set the device to search for and select
one of the available networks, or Manual to manually select the network from a
list. If the connection to the manually selected network is lost, the device sounds
an error tone and asks you to reselect a network. The selected network must have
a roaming agreement with your home cellular network.
Cell info display — Set the device to indicate when it is used in a cellular network
based on microcellular network (MCN) technology and to activate cell info reception.
Wi-Fi/WLAN connection
Your device can detect and connect to wireless local area networks (WLAN). Using
a WLAN, you can connect your device to the internet and compatible devices that
have WLAN support.
About WLAN
To use a Wi-Fi network connection, it must be available in the location, and your
device must be connected to the Wi-Fi network. Some WLANs are protected, and
you need an access key from the service provider to connect to them.
Note: Using Wi-Fi may be restricted in some countries. For example, in
France, you are only allowed to use Wi-Fi indoors. For more information, contact
your local authorities.
Features that use WLAN, or that are allowed to run in the background while using
other features, increase the demand on battery power and reduce the battery life.
