Google gives Voice to your mobile number
26th January 2011
Google Voice is a free service, but porting your existing mobile phone number will cost you $20. Number porting is available to existing Google Voice users right now – there’s a “Change/Port” option on the Settings page once you log in to your account – and according to Google, numbers are typically ported within 24 hours.
When you port your number to Google Voice, doing so actually cancels the existing service plan you have with your mobile carrier. So you’ll have to contact your mobile service provider to set up a new plan under a new number.
