When I got it to work on the first try, I did so by telling the nice woman (after I was super nice to her) this: "Yes, I was trying to add the 4G mobile hotspot add-on that was listed under the 'change features' tab when logged into MyVerizon online. But it told me that I had to call a CS rep." That probably gave her an indication of where to look for the add-on. So I would try that if I were you.
It's frustrating that my verizon data widget has not converted from 4G to Unlimited, even though I'm listed as "Unlimited email and web for smartphone" in my online account.
Did you try trashing the widget, then re-adding it to your home screen? Maybe a restart too, I can't remember but I think mine updated automatically, so I'm just guessing here.
