Google offers users a free phone number through Google Voice, and users can place and receive calls with this phone number. However, Google requires users to tie this phone number to an existing number, so users generally need a standard phone plan.
Google Voice allows users to select a phone number from a wide range of area codes. The service also provides voicemail and can even convert audio messages to text and send them to users via email or text messaging. Another benefit of Google Voice numbers is that users can send calls to their cellphones, landline phones or even to a computer or tablet.
