A data connection is automatically established when the online mode has been selected in the home screen settings. The home screen widgets can then automatically fetch the latest information from internet and show it on the home screen.
The automatic data connection can be disabled by selecting the offline mode in the home screen settings:
- Select Options > Content to offline mode
Note that the data connection may be opened automatically also by some other applications, for example by the email clients. The home screen setting doesn't affect the connections opened by these applications.
To disable the automatic email updates, go to email settings and change the synchronisation frequency (e.g. by selecting Sync frequency > Update interval > Manual).
