At the bottom of the browser window you can see all of the different Stack Exchange sites (you probably already knew that) The closest thing that I can see would be electronics, but that probably wouldnt work.
Personally, I work in telecom and know that the operators have started losing money with the "all you can eat" data plans, since users (you and I included :) ) have started getting carried away with it. Also, there is something called tethering, whereby you can connect a PC to your mobile phone and use its for data transfer, which can be a much higher data rate than expected from mobiles. I think also lately that many operators have started trying to detect that and prohibit it.
I know my answer got a bit off-topic, but I dont think there is anything else available on Stack Exchange to answer your question. Maybe you could call a new Area 51 site
