any unwanted data downloads and synchronisations. Contact your network operator
if you need detailed information about your subscription plan and data traffic costs.
When data traffic is turned off, you can still use Wi-Fi® and Bluetooth™ connections. You can

data transmission charges may apply. Contact your network operator for more

notification, for example, when sending search and synchronisation requests. Additional

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.
