Wireless network coverage

If your device normally connects to a CDMA network and your device supports international roaming, you might need to get a SIM card that is set up for international roaming from your wireless service provider. Your phone number stays the same when you travel internationally.

For more information about roaming and roaming fees, contact your wireless service provider.

To perform this task, your wireless service plan must include this service and your BlackBerry® device must be connected to a GSM® or UMTS® network.

Your device is designed to switch to an appropriate wireless network automatically when you travel.

1.On the Home screen, click the Manage Connections icon.

2.Click Mobile Network Options.

3.Change the Network Selection Mode field to Manual.

4.Click Scan for Available Networks.

5.Click a wireless network.

6.Click Select Network.

7.Press the Menu key.

8.Click Save.

To connect to your wireless service provider's wireless network again, change the Network Selection Mode field to Automatic.

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.
