Some users say that Project Fi can be used temporarily when restarting the phone or switching flight mode, but it can not be accessed in less than 2 minutes.

Google's team is aware of the problem, but the failure has not been solved for a day.

Data terminals of this size have a small chance of happening, but have a huge impact on the users who are traveling.

Google Project Fi is able to switch between cellular and WiFi hotspots to control data usage and reduce phone bills.

It chooses the strongest signal to switch between Sprint, T-Mobile and more than a million free and open WiFi hotspots. The monthly service charge is $ 20, plus a data usage fee of $ 10 / 1GB.
