Where is a truly free reverse cell phone look up?

Before I answer this question, I need to know something else from you. Does a free trial qualify as "free"? With that, you would have to have your credit card number ready so that you can't re-use the trial over and over again. Cell phone numbers are currently not published in the USA, so data brokers have found a way to make money. They pull information from as many free sources as possible and put it into their own database, which is searchable by members only. It costs money to have such a site running, so it wouldn't make much sense for this kind of a website to be free. Watch this video to have an idea of what the results are for a reverse phone lookup. 

You could speed up the playback of the video too, since it's pretty mildly helpful and not very interesting, if you even bother to watch it.
