Free Cell Phone Reverse Look Up

Is there a reverse cell phone look ups for free?

I need to know why this person keeps Texting me and i dont know who and its really annoying me so if there are any please tell me. I've tried whitepages.com

I know it does not look back up your mobile phone free or for a price. I was told that this is in violation of any FCC rule. I do not know for a fact, but I have looked around and that is the only answer I came up. If you ever find one, please share with me. fnx72 deserves the best answer. I have been trying to find a link for a long time.
