I already added a line and bought the phone. So tomorrow I'm going into a Verizon store with a hotspot to swap onto the voice line I created. Same deal from last year. Hopefully no issues.
It will be interesting what your store says, the Verizon corporate store I went to the manager claimed that she couldn't do what I was asking and that it wasn't possible which I'm sure is BS since it sounds like you can on the phone.
