today renamed its MVNO, Project Fi, to Google Fi. Along with the name change comes dramatically expanded compatibility with phones. Moving forward, the service will work with most Android phones as well as the Apple iPhone. The process of activating Fi on Android devices will be straightforward. Google says compatibility with iPhones is in beta and will require people to jump through a few more hoops, including the use of an iOS app. Basic service will be available to the majority of devices. Fi operates on T-Mobile, Sprint, U.S. Cellular, and WiFi, dynamically jumping to the strongest connection. Subscribers will need specific phones, listed on the Fi web site, to get this benefit, as proper LTE support is required. Google recently added VPN protection to Fi. The base service costs $20 per month for unlimited voice and text. Google charges $10 per gigabyte of data. People interested in the service will need to order SIM cards from the Google Fi web site. The service does not require contracts.
