When news first broke about the partnership with Google Voice and Sprint, many were wondering how it would be pulled off, and others were left jealous that it wasn't with all carriers.

You'll have the option to either keep their current number and use it as Google Voice, or use their Google Voice number on their Sprint device. If you haven't already, be sure to check out all the details, and get yourself enrolled today!
