Get Google Voice, Keep Your Mobile Number
Mobile users who would like to switch their voice mail to Google voice can now do so, without losing their existing mobile number. Previously, "Going Google" required using a Google-supplied telephone number.
However, those who keep their current mobile numbers will miss some of Gvoice's most advanced features. Nevertheless, Gvoice offers--for free--voice mail features that most mobile users have previously only been able to dream about.
