Remember, a critical part of Google Fi is that it&#x27;s supposed to automatically switch your voice and data to WiFi, and that Google has rigged partnerships such that they have lots of WiFi available for you to use.<p>So, if you currently use 5-10 GB&#x2F;mo on one carrier, the theory is that you&#x27;ll use less - possibly significantly less - on Google Fi.<p>That&#x27;s SIGNIFICANTLY different from what you can see reported about how you manually configure the WiFi you have used today.
