We have google fi as a travel phone. Our D took it to Africa and we could track the phone and see her location. We bought a google fi compatible phone so it would have technical support available if needed. She was in rural areas, and some of the nonprofit offices she was working with had unreliable internet connections - but she would just pull out her phone to open up a hot spot and the whole office could run over her phone for the day. Everyone there was very impressed with its reliability and speed. We used it in Maine when our regular phones didn’t have coverage for some reason and Canada, too.
I really like that the operating system works like a desktop in the sense that different users can log in with their google accounts, have their own contacts, etc. and then log out for the next person to use.
