From what I understand, Google's ProjectFi is a unique WiFi-first service that prioritizes calls and text messages to be done over WiFi and not data. Whenever you're around trusted open WiFi hotspots, the phone will automatically connect to them thanks to a feature called WiFi Assistant. If you're not around WiFi for whatever reason, Fi will switch to either Sprint or T-Mobile depending on which has the stronger cellular signal. Fi is only compatible with a few phones.
We would like to learn more if anyone from Google wants to reach out and work with us. I think we have some valuable data that might help customers decide which carrier has the best coverage.
