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. Your wireless service provider must 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 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.

Switch wireless networks manually

Verify that your wireless service provider has set up your SIM card for this service.

By default, your BlackBerry® device switches to an appropriate wireless network automatically when you travel.
