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 coverage area. If your device requires a SIM card, your wireless service provider might have to set up your SIM card for
roaming services before you can use a different wireless network.
An indicator appears on your device to let you know that you are roaming outside of your wireless service provider's wireless coverage area.
You might also have to provide login information before you can access the wireless network. For more information about roaming, contact
your wireless service provider.
