Google Fi is great if you spend 95% of your time in Wifi capable areas (which most do). The only time I use data is if I'm in the car by myself, but usually we use the Wife's phone which is on Verizon for navigation and such (she gets a discount from work). Google also reimburses you for data not used throughout the month so my bill usually hovers around $26 a month inclusive of the data back. The only downside for me was having to purchase a phone outright. Other than that is been great and seems to be getting better all the time, but Im an old school bare-bones phone guy so I don't need bleeding edge features.
