Sometimes you'll need to forward all your incoming calls to a different phone number. For example, if you're traveling overseas or can't use your phone for some period of time, you can have your iPhone forward the calls to a work or home number so people can reach you. Here's how you do it:
- Open the Settings app and select Phone >Call Forwarding.
- Switch the Call Forwarding button to the ON position.
- In the Fowarding To section, enter the phone number to which you want your calls forwarded.
- Tap Call Forwarding to return to the Call Forwarding Screen. A small phone icon with an arrow will appear at the top of your phone screen, indicating that call forwarding is turned on.
