To port your personal Google Voice number:
- On your computer, open Google Voice.
- You'll be prompted to pick a new number, but your ported number will soon replace it, so it won’t matter what that number is.
- At the top left, click Menu > Legacy Google Voice. Google Voice will look different, but you're in the right place.
- At the top right, click Settings > Settings.
- Click the "Phones" tab.
- Next to your current number, click Change / Port.
- Select I want to use my mobile number. Follow the on-screen instructions to set up your new number.
