If your usage is detected by US Cellular's Fraud Team (that is what you are committing BTW), you could be suspended or even cancelled for violating the Terms of Service.
I believe that the header info on IP packets sent via a Windows or Mac computer are different than those sent via an Android/Linux phone. Also, if you are streaming TV, you will hit that 5GB far sooner than just checking your email.
Luckily, with US Cellular's cap, you will probably only have to pay $200 max overage, if you go over the 5GB, and worst case, ETFs if you are cancelled for fraud.
