There is NO "3G data plan" or "4G data plan" from Verizon, at least not if you currently have an "older" data plan. Since you have an unlimited plan, you fall in that category. For you, NOTHING will change except for your phone and the speed that you can browse at. When you activate your phone (I believe you STILL have to call in to activate the SIM), do NOT let them "change" or "upgrade" your data plan. Don't let them scare you into thinking you have to.
