If you ever needed to find a cell phone number, you probably did not really know where to start. The problem with mobile phone numbers is that they are not publicly listed as landline numbers. You will not be successful in trying to find them one of the many free directories on the internet.
However, and this is the good news, there are free methods to look for mobile phone numbers.
First, use a search engine such as Google or Yahoo. Many cell phone numbers are advertised by their owner without having noticed that they are located as a search engine. This can be used for you. Just enter the number you want to search for the search engine you want. Keep in mind that you use bid estimates to improve the quality of your results. You may need to browse the first ten to twenty pages of search results to see if any of these are relevant to your search.
If the search engine did not find the number, try using the mobile phone directories. Unfortunately, however, these libraries have only a very limited number of mobile phone numbers. People need to type their own number voluntarily to list and, as you can imagine, this does not happen very often. Can you enter your private number in a directory that is available to millions of people around the world? I do not think so.
These limited opportunities to search for a cell phone number are the cause of the professional reverse lookup directories that are becoming more common. These sites each year buy hundreds of millions of mobile phone numbers from mobile phone providers and therefore the chances of finding the number you are looking for are high enough to use these services.
