I would like to sign up for a Google Voice number, so that I can send and receive SMS text messages on my computer.
When I select a Google Voice number (for example, (555) 123-4567), Google tells me that "To complete setup and start using Google Voice, you need to verify your existing phone number."
I do not want to tie my existing phone number (mobile number) to my Google Voice number -- I want to keep them separate. Will providing my existing phone number for verification tie my existing phone number to my Google Voice number? Or is it simply to verify that I am a real person?
