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.

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.
