charges may apply. Contact your network operator for more information.

notification, for example, when sending search and synchronization requests. Additional charges

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.
