Google first announced Project Fi in April 2015 with only a limited number of Android devices which has support for it. Now, they are expanding the support to more Android and Apple devices. The tech giant has also revised the Project Fi name, calling it Google Fi.

Google Fi is a virtual mobile network operator by Google which started off as Project Fi. It was first limited to devices from Google before making it available to a wider range of devices today. Google makes use of both WiFi and cellular networks from US carriers namely Sprint, T-Mobile and U.S. Cellular. Phones which are designed for Fi can take advantage of Google’s own mobile network for a much better mobile coverage and service. Google Fi is able to switch networks seamlessly by detecting strong mobile networks and WiFi hotspots around you.

However, Apple users can expect poor service at the moment since it is still in the beta phase. Android devices which are not listed but compatible with Google Fi are not guaranteed to make full use of the features available. For a list of devices which are designed for Fi can be found at Google Fi’s website. You may also check if your device has support for it at the website too.
