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.
