tone and asks you to reselect a network. The selected network must have a roaming
agreement with your home 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 Wi-Fi/WLAN
To use a wireless LAN (WLAN) connection, it must be available in the location, and your
device must be connected to the WLAN. Some WLANs are protected, and you need an
access key from the service provider to connect to them.
Features that use Wi-Fi/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.
Your device supports the following Wi-Fi/WLAN features:
● IEEE 802.11b/g standard
● Operation at 2.4 GHz
● Wired equivalent privacy (WEP) with keys up to 128 bits, Wi-Fi protected access
(WPA), and 802.1x authentication methods. These functions can be used only if they
are supported by the network.
Important: Always enable one of the available encryption methods to increase
the security of your wireless LAN connection. Using encryption reduces the risk of
unauthorized access to your data.
WLAN connections
To use a wireless LAN (WLAN) connection, you must create an internet access point (IAP)
for WLAN. Use the access point for applications that need to connect to the internet.
A WLAN connection is established when you create a data connection using a WLAN
internet access point. The active WLAN connection ends when you end the data
connection.
You can use WLAN during a voice call or when packet data is active. You can only be
connected to one WLAN access point device at a time, but several applications can use
the same internet access point.
When the device is in the offline profile, you can still use WLAN (if available). Remember
to comply with any applicable safety requirements when establishing and using a WLAN
connection.
Tip: To check the unique media access control (MAC) address that identifies your
device, open the dialer and enter *#62209526#.
