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.
