I signed up for Google Fi phone service, but support explained that app can be activated only inside the US and then it will work worldwide.
I am overseas and do not plan to visit States in near years.
I want you to create new profile in your supported Android phone, login as me, download Google Fi and activate service. Then you wipe the additional profile and return to yours. I download app here and hopefully it will work.
Before bidding, please check your device is supported on Google Fi website!
