Google has announced that it is opening its Project Fi mobile network to everyone in the U.S. Project Fi is the Internet giant’s virtual mobile network that uses open Wi-Fi hotspots and cellular networks belonging to Sprint and T-Mobile to provide voice, text, and data services to users. The service allows users to make phone calls and texts even while only on a Wi-Fi connection. Previously, Project Fi had been an invite-only service.
Besides the ability to make calls and texts over Wi-Fi networks, another headline feature of Project Fi compared to other mobile networks is its pricing structure. Users pay $20 a month up front for unlimited domestic talk and text and unlimited international texts as well as an additional $10 a month for every GB of data they want to use. However, at the end of the month, any unused data gets credited back to their account.
