If you’re a fan of Google Voice and a Sprint wireless customer, today you have good reason to celebrate; Google and Sprint have joined together to give users unprecedented Google Voice customization on their mobile phones.

Here’s how it works: if you have a Sprint mobile phone, you can now choose to use your existing mobile number as your Google Voice number, or to have your Google Voice number take the place of your Sprint phone number.  Whichever option you select, the number – when dialed – can be configured to ring multiple phones (your Sprint phone, home, office, vacation home, etc.) so you never miss a call.  Google Voice voicemail service will replace the existing service, and the same basic Google Voice features remain such as transcribed voicemail, email and/or text message alerts, etc.  International calls will also be made using your Google voice number for reduced per minute fees.

This service is compatible with all Sprint-branded handsets, including Sprint Android phones. 

While the service is free, minutes used continue to be deducted from your monthly voice allotment.  You must have a Google Voice account as well.
