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 use only 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 special ways when roaming.
