So I have t-mobile, but am looking into getting an unlocked phone from either Amazon or BestBuy. I was looking at a Palm, specifically Pixxi Plus, but I know since it has internet, you need a data plan with a service provider. All I want to do with the phone is talk and text just like any basic phone so I was wondering if a data plan is required for an unlocked phone even if I am not going to use email, web, apps, ect.
