What is the Cellular Usage Index (CUI)?
Itﾒs our geeky way to quantify your cellular footprint. We employ an index to normalize things in a world where texts use up a lot less cellular capacity than minutes. Your CUI is calculated using your last seven days of activity.
Hmm, I tend to keep phone conversations brief, I do not text, period, and I currently have no data plan at all. I'd imagine my "cellular footprint" to be quite low, at least now. This may turn out to be a good deal for me.
