Roms that don't report data usage? topic

I use my wifi tether a fair bit. I'm about a week and a half into this months billing cycle and I'm sitting at 11.6gb. I use it for my kids tablets, our dtv dvr, and misc other things. I'm looking to see if there are any good stable, and fast roms that have tethering enabled and do not report data usage.. A friend of mine has the S5 and said that his doesn't report. He is already up to 83GB of data, and it's like that every month. I know that mine does report because I can log into my sprint account and it shows.

Any recommendations?
