About global roaming mode

If your BlackBerry® device normally connects to a CDMA network, your device is designed to connect to an appropriate CDMA, GSM®, or UMTS network automatically when you turn on global roaming mode and travel.

Your wireless service provider must provide you with a SIM card that is set up for global roaming services before you can connect to a GSM or UMTS network. When you insert the SIM card, your device switches to global roaming mode automatically. When you remove the SIM card, your device scans for CDMA networks only. Your phone number does not change when your device switches to global roaming mode.

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