Google Voice gives you one number for all your phones -- a phone number that is tied to you, not to a device or a location. Use Google Voice to simplify the way you use phones, make using voicemail as easy as email, customize your callers' experience, and more.
Google Voice isn't a phone service, but it lets you manage all of your phones. Google Voice works with mobile phones, desk phones, work phones, and VoIP lines. There's nothing to download, upload, or install, and you don't have to make or take calls using a computer.
Asking $10 obo to save you the wait.
