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.

device is in global roaming mode and that your SIM card is inserted in your device correctly.

• Verify that you have turned on the connection to the wireless network.
• Verify that you are connected to your wireless service provider's network. If you switched wireless networks manually,

your device remains connected to that wireless network until you select your wireless service provider's network again.

• If you have set a specific speed for wireless network connections, verify that you are in a wireless coverage area that

supports the connection speed.

• If you have a Wi-Fi® enabled device and your wireless service provider supports UMA, verify that your connection

preference is not set to Wi-Fi Only.
