About wireless coverage indicators
Indicators in the top right-hand corner of the Home screen display the wireless coverage level for the area in which you are using your
BlackBerry® device. For more information about wireless coverage areas, contact your wireless service provider.
The indicator that displays five ascending bars provides information about the strength of the wireless signal. Three or more bars indicates a
strong signal. A reduced signal display might indicate increased power output from your device as it attempts to connect to a weak signal.
If the wireless coverage indicators display anything other than 1XEV, 1X, 3G , EDGE, GPRS, NXTL, MIKE, or NTWK, you might be in an area
of reduced wireless coverage where features such as email messaging and internet browsing are not available (you might only be able to make
a phone call or send and receive SMS text messages). If the SOS wireless coverage indicator appears, you can only call emergency numbers.
If the X indicator appears, you are in an area of no wireless coverage.
If your device includes Wi-Fi® support, a dimmed Wi-Fi logo with a network name displayed at the top of the screen indicates that your device
is connected to a Wi-Fi network but does not have access to BlackBerry services such as email messaging and internet browsing over the Wi-
Fi connection.

Preferred wireless network list
About the preferred wireless network list
Your wireless service provider might have agreements with other wireless service providers that permit you to use their services when you are
traveling. You can use the preferred wireless network list to control the order in which your BlackBerry® device uses these other wireless
networks.
Your device tries to connect to a wireless network based on the order in which the wireless networks appear in your preferred wireless network
list. When you travel, your device scans for the wireless networks on this list first. If no wireless network on the list is available, your device is
designed to connect to another available wireless network automatically.
Note: Extra fees usually apply when you roam. For more information about roaming fees, contact your wireless service provider.
