I downloaded all of out calls to an excel spreadsheet because I was trying to figure out how many minutes we need when we switch carriers. I noticed that at random times during the day it charges us a minute for data. At first I thought this might be a picture message coming through, but then I noticed some at 2am when the phone was on but no messages were coming through at all. It also happens on the call list for my Dad's line. He only uses the phone as a phone. He doesn't know how to text at all let alone picture message. Anyone have an idea what it could be? Here's a screen shot of the excel spreadsheet.
