The main reasons why people do reverse cell phone lookups are as follows:

• To check on their spouses - are they cheating on them? Who are they speaking to at those odd times of the night?
• To catch prank callers

What's the best method to trace a cellular number? 7-8 years ago, the only way you could trace anybody's cellular number was by consulting a private detective.
They typically charge you over $100 and take a little bit of time to get back to you.
However, today there are many manually built online databases on the internet that you can access from any computer with an internet connection.
This is by far the best method for a cell number reverse lookup.
It can give you accurate and reliable information about the name, address, age, family members, neighbors, associates etc.
of the phone owner.
It's amazing how much info you can get within a couple of minutes.
How about the white pages? White pages only has land numbers.
Mobile numbers are not published on any of the free public phone directories to comply with the existing privacy laws.
Mobile numbers are considered personal information in contrast to land numbers.
That's why you haven't seen a Verizon or Sprint or any other mobile phone directory.
Is it Free? If wireless phone user details are made available for free of charge, then the whole concept about wireless phone subscriber privacy rights break down.
The information will quickly get into the hands of telemarketers and other predators (e.
g.
identity thieves).
This is why you won't be able to get this information for free.
However, if you only need to lookup the wireless carrier and the location (city, state), yes you can get that information for free.
