text: what site/service is the best for tracing a cell phone number? i keep getting harrasing calls.? i have tried intelius, and the number is not listed in their database.  i have done some research on the net, but a few of those "information" sites seem like rip-offs; are there any valuable sites or brick and mortar companies that can provide me with the name and other information on the person that keeps harrasing me?  thanks! just look on your online billing they will show you the numbers of the incomming calls, if its a private or unavailable number just dont pick up.
