So I see that Google Fi has expanded to support my phone. Does anyone have experience with it on a non-designed for Fi phone?
More like, the spectrum is all over me! Having done research, I realize my error in thinking that Google Fi was Google's fiber network, and that it actually is available in my area. Google's coverage map seems to follow the major highways. I do wonder what the difference is, between the "designed for Fi" phones and the "Fi Compatible" phones, since the coverage map looks ten times smaller for the latter, than it does fore the former. The point is moot for me, since I am on a Nokia 6.1, which is GSM only, so I'll live forever in the land of the AT&T, Cricket, and T-Mobile networks, until I need a new phone.
Designed for Fi are phones like the Pixel 3 that have CDMA and GSM compatibility. They can switch between netoworks to get the best coverage.
Hmmm. You could get creative, and install a router at the entrance to your driveway, and run 800' of cat-6 ethernet cable yourself... Have fun rebooting the modem on a regular basis.
