If you've used Google Voice, Google's app that provides select phone services, then many of Fiber Phone's features will be familiar to you. You'll get cheap international-calling options and be able to choose your own phone number, and your voicemails will be transcribed and texted to you. It also includes spam filtering and a "do not disturb" function.
Fiber Phone will be available only as a $10-per-month add-on to people who already have Google Fiber's internet service.
And, like Google Voice, the phone number you choose can be set to ring on different devices. You could set it to buzz your landline if you're home, your mobile phone when you're out, and your office phone if you're at work.
In a blog post announcing the service, Google said that Fiber Phone will be available only in select areas, though it didn't get specific.
Google's larger Fiber service is available only in four cities - Provo, Utah, Kansas City, Missouri, Austin, Texas, and Atlanta. Google has said that the service is coming to seven more cities, but for now we'll have to assume Fiber Phone will launch in one of the current Fiber markets.
