Turning off data traffic

You can disable all data connections over 2G/3G networks with your phone to avoid 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 also send and receive multimedia messages.

2Find and tap Settings > More… > Mobile networks.

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 synchronisation requests. Additional charges may apply for data roaming. Consult your service provider.

To activate data roaming

1From the Home screen, tap .

2Find and tap Settings > More… > Mobile networks.

3Mark 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 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.

To select a network mode

1From your Home screen, tap .

2Find and tap Settings > More… > Mobile networks.
