If you are looking for a quick, reliable and fast way to trace a mobile phone number, then you may have to sign up with a paid reverse phone lookup directory as there are no free directories for mobile phone numbers. Fortunately there are some very cheap reverse phone lookup directories where you can get all the details behind a cell phone number under five minutes and you will not have to pay if you are not totally satisfied with the service.
But How do these directories get the information?
Although cell phone users’ details are not listed on public directories, they are still available in the internal us mobile phone number database of the telecommunication companies and there are companies who pay large amount of money to legally buy access to this database who are able to make the information available to you and me for a little fee.
How much is this fee?
The price varies from directory to directory. The service I use charges $14.95 per search and they have a very unique service that allows you look up as many phone numbers as you want for just
It is cheap, reliable and it provides a comprehensive details of the owner of the number you are tracing
It can be done under 5 minutes
It can be done by any one who have a computer and internet access
What Do I need In order to use these paid directories?
The 10 digit phone number ( this plus the area code) and a very good and reliable reverse phone lookup directory or site.
It is easy to find the phone number but it can be difficult to find a Google and reliable reverse phone lookup site or directory As There are so many reverse phone lookup directories available on the internet and it can be difficult to know which one if good and which is not.
Below are some of the things you should keep in mind when choosing a reverse phone lookup directory: 
Sign up only with a directory that has a large database of phone numbers. A directory with a small database of phone numbers reduces you chances of getting the details behind the particular phone number you are looking for. The directory I use and recommend has over 200 million US household phone numbers in its database.
Look for a directory that allows a free demo or teaser search. A demo a teaser search is meant to run a free search on the database to see if the details of the number you are trying to trace is available or not.
Another very good way to know if a reverse phone directory is good or not is to read user reviews on the internet. You must however note that many these reviewers are affiliates who will earn some money if you buy the product which is why you must only look our for facts and not opinions.
Another thing is never to sign up with a directory that does not have a good money back guarantee. Signing up with a service or directory with no money back guarantee is like going to war without proper preparation.
There is one service I have used that has always given me additional information such as satellite maps of the location, known neighbors and relatives, other numbers by the owner and in one particular case, that I found quite beneficial, was when they also gave me a person’s address history.
