When you added the hotspot feature, did you change your data plan to one of tiered data plans that included the hotspot feature? Or did you add the hotspot feature under the add features option?
What is the name of the data plan you currently have?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
when you say "go back" to unlimited data, it leads me to believe that you currently don't have unlimited data. if that is the case, then no, you can't go back to unlimited data.
