Nokia 5230 - How do I use call divert on my Nokia Symbian device?

Select Menu > Settings > Calling > Call divert (or Call forwarding).

Call divert allows you to divert incoming calls to your voice mailbox or another phone number. The voice mailbox is a network service, and you may need to subscribe to it. For more information contact your service provider.

To activate call divert, select the call type and then Options > Activate.

To check whether the option is active for a given call type, select Options > Check status.

Several diverting options can be active at the same time. When all calls are diverted, the call divert indicator is displayed in the home screen.

Call barring and call diverting cannot be active at the same time.
