When I got my iPad 3 on launch day, I signed up for Verizon's 2GB data plan in the Settings app. Now I have 2 iPhone 5s on a shared data plan with Verizon, and I'm thinking about canceling the iPad's separate plan and adding it to the shared plan with my iPhones. Is there an advantage either way, adding the iPad to the shared plan vs keeping it on its own plan? I don't use a whole lot of data on the iPad so I figured I might be able to save a few bucks each month by combining them.
