Data traffic

Turning off data traffic

You can disable all data connections over 2G/3G networks with your phone to avoid any unwanted data downloads and synchronizations. Contact your service provider 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.

To turn off all data traffic

1From the Home screen, drag upwards.

2Find and tap Settings > Wireless & networks > Mobile networks.

3Unmark the Data traffic checkbox.

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.

To activate data roaming

1From the Home screen, drag upwards.

2Find and tap Settings > Wireless & networks > Mobile networks.

3Mark the Data roaming checkbox.

You cannot activate data roaming when data traffic is turned off.

Network settings

Your phone automatically switches between networks depending on availability. Some network operators allow you to switch networks manually, for example, if you are travelling abroad and want to use a particular network.

To save battery, you can limit your phone to only use GSM networks. Data downloads and uploads will however be slower. If you are going to download or upload large amounts of data, we recommend that you change to another network mode or connect to the Internet through a Wi-Fi® network.

To use GSM networks only

1From the Home screen, drag upward.

2Find and tap Settings > Wireless & networks > Mobile networks.

3Tap Network Mode.

4Select GSM only.

To select another network manually

1From the Home screen, drag upwards.

2Find and tap Settings > Wireless & networks > Mobile networks > Network operators.

3Tap Search mode.

4When a popup window appears, tap Select manually.

5Select a network.

If you select a network manually, your phone will not search for other network, even if you move out of range of the manually selected network.
