Data Roaming; Network Settings - Sony Ericsson Xperia active Extended User Manual

Data roaming

Depending on your network operator, it might be possible to allow mobile data connections
via 2G/3G outside of your home network (roaming). Please note that data transmission
charges may apply. Contact your network operator for more information.
Applications may sometimes use the Internet connection in your home network without any
notification, for example, when sending search and synchronization requests. Additional charges
may apply for data roaming. Consult your service provider.
To activate data roaming
1 From the Home screen, tap
2 Find and tap Settings > Wireless & networks > Mobile networks.
3 Mark the Data roaming checkbox.
You can't activate data roaming when data connections have been deactivated

Network settings

Your phone automatically switches between networks depending on available networks
over different locations. Initially, your phone is configured to use the fastest mobile network
mode available for data. But you can configure your phone manually to only use a slower
2G network mode for data, to extend the life of your battery between charges. You can
also configure your phone to access a different set of network modes entirely, or to behave
in particular ways when roaming.
