Project Fi will also incorporate Wi-Fi to ease the data burden, switching between Wi-Fi and cellular networks on the fly, and giving users automatic connectivity to over a million public hotspots. Google says it will encrypt data connections to enhance security.

The Project Fi site shows that Google is offering coverage nationwide, although whether or not you’ll have 4G LTE connectivity varies by region, as it also does with the major carriers… see more
