To start, go to the home screen on your iPhone and open the Settings app.
Scroll down until you find "phone" and give it a click.
Here, you will see several options. Scroll down and click on "call forwarding."
To the right of "call forwarding" there will be a toggle. Click it to turn on call forwarding.
Now, we need to click "forward to," so that we can add in the call forwarding number.
Lastly, type in the forwarding number and click the arrow in the upper left-hand corner to go back to the previous screen.
That's it! You set up call forwarding in under a minute. Now, try it out!
