The only problem is that the world is not perfect, and we, in fact, like in a world laden with commercialism - practically anything, everything, and anyone can be sold. Take, for example, the matter of cell phone service providers. Not only will they milk you of your money in the form of monthly bills and pre-paid credits, they also sell their subscribers' database to reverse lookup companies.

But there's really nothing wrong with cell phone companies doing this. We're simply affirming that you shouldn't expect help from your cell phone company if you're assuming an unknown number of your husband's cell phone number. If you want to know who your husband has been talking to for long hours inside the bathroom (you heard a faint moan when you leaned your ear against the bathroom door), then you better pay the price for finding out who.

Cell phone numbers are not included from the common directory and directory assistance services. Someone once proposed to index mobile phone numbers in a directory listing by names from A to Z. But this was canceled amidst the fuss that having this kind of directory listing would break down protection from troublesome telemarketers.

Thankfully though, while there's little hope of ever having an organized cell phone directory that you can flip with your fingers, at least reverse lookup companies offer cell phone subscribers the chance to look up suspicious numbers for a small fee. The databases of these companies are admirable - they can have millions of cell phone numbers in their databases.

A few reverse lookup companies aim to offer you a free search, but these searches are often for landline numbers, which is information that you can really lookup in a directory. An excellent reverse lookup company can cost you $25 per search, though there are companies that offer their subscribers explicit number of searchers for a one-time fee. The prices may vary but you can expect to pay $59.

If reverse look up companies are just not your type, there are, of course, some things that you can do. In fact, you can Google the number in query and hope that the information on that number is publicly opened. You can also sign up to be a member at a free cell phone directory website. The only problem is that the numbers provided in those websites are only volunteered by members, so the information that you find on there is not really extensive.

If fees are your complaints to reverse lookup companies, then try finding a company that aims to provide a free reverse lookup. You may, unlikely, find yourself hopping from one service to another. And you might just find that you always get what you pay for - if you pay nothing, then you get nothing.
