The problem is that to get a postpaid account you have to pass a credit check. That wouldn't be possible, I don't think, for foreigners. Maybe if you worked for a large company, they could qualify and get the account in their name. IOW, it's not the fact you are foreign is the problem - it's the fact your name wouldn't appear on a U.S. credit report.
I don't know if you could post a deposit.
I'll make some inquiry in a couple weeks once this whole thing is in operation. I'll be testing it out in China and Hong Kong 10/26-11/8.
