Today Google officially announced their previously rumored entry into the world of wireless service. This new endeavor is known as Project Fi, and it's exclusive to owners of the Nexus 6 who live in the United States. While carriers have offered branded mobile devices at times, the entry of a company making mobile phones into the business of providing the wireless service for their own devices is unprecedented. But unlike Google Fiber, Project Fi is not Google's attempt to build a new wireless network in the United States. Rather, they will be acting as a Mobile Virtual Network Operator (MVNO) running on the T-Mobile and Sprint networks, as well as piggybacking off of open WiFi hotspots.
