User Guide Wireless network coverage 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.
