I don't know where you are, but I know you can't do that in Canada. All mobile service providers here require a basic voice package that the data plan must be added to. I imagine it's much the same in the US.
You could also get one of these suckers from Verizon. $60 a month for a pocketable wifi hotspot with a 5GB limit. If you're using it all day for the phone you're probably going to need to charge it 2-3 times per day or leave it plugged in at your desk, that sort of thing. But you can have up to 5 devices connected and using data at once.
