I have had some with use exceed 1GB used on cellular.
Holy smoke that is fast! My phone is only 4G and the fastest download test I got my result was 85.3Mbps and it uses 127MB data. I guess they always run the test for about 10 secs (5 sec download and 5 sec upload). That would explain the amount of usage going up as speed goes up.
