Just wanted to chime in with a personal experience. You may not be able to get away with this. I used to have unlimited data with Verizon. I thought I bricked my Galaxy Nexus one time, and went to put an old phone on my line to use temporarily. I got a message when trying to do so that I would have to change my data plan to do so. So I didn’t, I just got my Nexus working again. If you go to the store I think they have a back way to do it. But I wouldn’t be so sure about keeping your unlimited data.
