Need help figuring out how to play at work

[Chucck]

I know that if I was physically caught I could face discipline, but thats not really an issue.
If I used a 3g network(which when I referred to it, i basicly meant phone service, didn't know it qualified as actual internet) on my own computer, theres no traceable internet activity so I would be fine.
The only 3g capable networks I can find are Sprint/Verizon/ATT. They have the bandwidth cap so thats why I am asking if anyone stateside uses an aircard/phone service to play, how it works for them, and their package.
