I currently don't have data right now and I was looking over my Verizon account and in my Device Details it says "the number xxx-xxx-xxxx has used 0G of data as of January 6th" but it shows percentages of what I use the most on my phone. Is that showing what I was using when I had data or is that showing what I'm using when I'm on wifi? I don't have a particular reason to why I'm asking this question, just curious because it doesn't make it clear.
