Is there anyway of looking up who a phone number belongs to that appears on a phone bill? It's not what it sounds like, I paid my bill a minute ago and was just looking around online and found where I could view a text message log to each line on my account. I have a teenage son, 16, and there is a number that appears on his log pretty much every minute of the time he is awake for the past 5 days, even during school all day. Only stops while he is at baseball practice. So not suspicious spouse or anything, just a concerned mother.
