Project Fi does a few innovative things that set it apart subtly from other carrier offerings, and one of the lesser-advertised features is the ability to “pause” service on a whim without any hoops to jump through. Pausing service isn’t something offered by other carriers, and lets you simply disable your phone for as long as you want and instantly resume service with the press of a button.
This isn’t something you’ll be doing all the time on Project Fi, but it does turn out to be a neat feature. We’re going to show you how it works.
