Look at the name. I think their goal is that most of the time when you're out and about, you're connected to Wi-Fi. I think the cellular partners are a crutch to get them there. If they manage that, you'll wind up paying a lot less than with T-Mobile.
> There are lots of Wi-Fi hotspots out there but not all of them are high-quality. Project Fi automatically connects you to more than a million free, open Wi-Fi hotspots we've verified as fast and reliable. This technology helps keep your speed high and your data bill low.
For low bandwidth users a ~$25 / mo, intl coverage, no contract plan can be really attractive. I'm not sure how wifi coverage or handoff will perform in real life testing, but it's appealing to have Google pressure US telecom companies the same way they did with Google Fiber.
I usually don't have wifi while I am out and about, most stores at least require you to hit accept on their terms and conditions before you can actually connect. Maybe if they showed wifi hotspots on their coverage map I could get behind this idea.
Yeah, I don't know how they do this, but Google says they have pre-approved WiFi hotspots the phone will automatically connect to. From this, I wonder if security will be a concern for some of these hotspots.
