About roaming and international roaming
In most cases, your BlackBerry® device automatically connects to the appropriate wireless network when you travel outside
your wireless service provider's coverage area. Sometimes you might have to provide login information before you can access a
wireless network. When you roam, a triangular roaming indicator appears at the top of the Home screen.
If your device requires a SIM card, your wireless service provider might need to set up your SIM card with roaming services
before you can roam.
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.

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.
