This is what I just did and I agree, it worked fine. I didn't use it much but it was there when I did need it. The only issue I had was trying to send a text to someone specifically (I could send texts to others). As your phone connects to different carriers (I was sailing from island to island) you get a bunch of texts from Verizon telling you (again) about your Intl plan. In these texts are numbers to call for help. I called it and got an extremely helpful woman who helped me figure out that the reason I couldn't text this one person is because he likely didn't have his iPhone set to accept SMS messages if iMessage was unavailable (or something like that). Bottom line, Verizon support was impressively good.
