The invite has been rolling out for at least the past month to members of the Google Fiber Trusted Tester program. The Trusted Tester program involves Fiber subscribers who have opted in to try new and potential changes to their service.
Officially, Google Fiber does not offer traditional phone service. But if the company rolls out Fiber Phone more widely, Google would become a true triple-play provider, offering customers a mix of broadband, television and telephony — just like its rivals in the cable industry.
From there, it wouldn't be much of a leap for Google to begin offering its broadband subscribers bundled access to Project Fi, Google's recently launched cellular service that hops between Sprint, T-Mobile and WiFi. As many cable companies mull an entry into the competitive wireless market, it appears Google may already be positioning itself to get ahead of them.
