I had trouble laat year in a couple of remote places using Google Fi. They use Sprint and T-Mobile towers. I believe e.g. if you have a contract with Sprint, you can roam on Verizon's towers. However, I was visiting an area (central NC) and I had zero service the whole time, even in town. I switched back to Verizon.

Google Fi also automatically connects you to known WiFi spots and sends your data over their VPN. The switching between antennas will kill your battery as well.
