About roaming

In most cases, your BlackBerry® device automatically connects to an appropriate wireless network when you travel outside your wireless service provider's wireless network coverage area.

An indicator appears on your device to let you know that you are roaming outside of your normal network area. You might also have to provide login information before you can access the wireless network. Contact your wireless service provider for more information about roaming.

About global roaming

In global roaming mode, your BlackBerry® device is designed to connect automatically to an appropriate CDMA network or GSM network when you travel. Your wireless service provider must provide you with a SIM card that is set up for global roaming services before you can use a GSM network. When you insert the SIM card, your BlackBerry device automatically switches to global roaming mode. When you remove the SIM card, your BlackBerry device scans for CDMA networks only. If you switch between a CDMA network and a GSM network, the phone number for your BlackBerry device remains the same.

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