So you give people the GVoice number, and push that to your cell phone. If you change providers, change numbers, change whatever...you don't have to do anything except change the number assignment in GVoice. No one has to know.
And if you find the new phone number is getting wrong numbers from folks who think they are still calling the old owner? GVoice can block those calling numbers--and just those callers--so you don't pay for their calls, either.
An incredibly powerful service, and an example of what ANY telco or celco could provide for your phone, if they really wanted your business instead of your wallet.
