Even with unlimited data, unless your mobile data speed is ~3 Gbps, you don't have 1 PiB of data per month. At most, you have 31 TiB (assuming constant 100 Mbps throughput for 30 days, 24/7).
Touché.

So clarify my dumb question, you dont need to have Sprint or TMobile to utilize this? I would basically cancel my ATT and join this Google Fi stuff.
Seems Texas is all LTE or at least on their coverage map where I am in the DFW area which is awesome.
Correct. You do not need TMo or Sprint. Google is using their networks (much like Metro PCS or Cricket does.) Difference with Google Fi is dynamic switching between CDMA and GSM, plus WiFi (effectively giving users a much larger swath of LTE coverage ). As far as I know, no other company has done this?
