Thats how I found out about my H affair by checking his cell phone records. I saw he was getting alot of calls from a certain number and they were long phone calls. He tried to hide it from me by telling the phone co. to stop sending the detailed message page of our bill back in Nov. of '06, and to just send the amount due page. I asked him why he did that and he said to save paper and I was always so trusting of him I believed him. Then one day when I got suspicious and I went on the verizon website and looked at the bill details and I knew something was up. It took me about 6 mos. to figure it out.
