Let me know if I have missed any device resolution.

Blackberry Network connectivity

If you are receiving network errors even when your mobile device indicates that signal strength is good, check that you are not connected to a roaming network.

What is Roaming?

When you are roaming, you are outside of your network’s normal coverage area and are receiving coverage from a carrier partner. Many roaming network carrier partners provide only voice connectivity so data from the Internet is unavailable even if you see a strong signal. If this is the case, you will not have a data connection until you move to an area where you have full coverage from your carrier or a carrier partner that offers full coverage.

How Can I Tell if I am Roaming?

When you are in a roaming network, you will see a special symbol on your mobile device’s Home screen. The following table provides examples of roaming symbols for different mobile devices:

Model	Symbol
BlackBerry® 8100, 8300, 8700, 8800
BlackBerry 8900, 9000

How to Prevent Roaming

Accessing a network while roaming can incur unexpected charges. Set connection to mobile networks to Manual to prevent unwanted connections and roaming charges:

1. Highlight and select the Manage Connections icon on the Home screen.
   
   
   
   
2. Highlight and select Mobile Network Options.
   
   
   
   
3. Highlight and select Manual or Data Services Off When Roaming (depending on your model).

How to Check Internet Connectivity

Your mobile device displays one of the following symbols when connected to the Internet:

8100, 8300, 8700	8900, 9000	Description
3G	3G	3G network connection
EDGE	EDGE	EDGE network connection
GPRS	GPRS	GPRS network connection
3g Edge GSM gprs	1X D 3g edge Edge GSM gprs	Phone and SMS text messages only
		Wireless connection off
		Outside of wireless coverage area
		Wi-Fi network connection
None	None	Airplane mode is enabled

How to Toggle Wi-Fi Mode

1. Highlight and select the Manage Connections icon on the Home screen.
   
   
   
   
2. Highlight and select or clear the Wi-Fi check box to enable or disable Wi-Fi. See your BlackBerry users manual for instructions on setting up Wi-Fi networks.
   
   
   
   

How to Toggle Airplane Mode

When you enter environments, such as an airplane, where you need to disable everything that sends a signal, put your mobile device into Airplane Mode.

1. Highlight and select the Manage Connections icon on the Home screen.
   
   
   
   
2. Highlight and select Turn All Connections Off to enable Airplane Mode. Select Restore Connections to disable Airplane Mode.
