As you probably may already know, cellular numbers are not published on phone books.
This makes tracing mobile phone numbers, quite challenging, however not impossible.
Why aren't Telemarketers calling your cell? If you have ever wondered why you don't get telemarketers calling on your cellular phone, that is because your cell number is considered personal information and it is not legal for telemarketers to call you.
There are specific privacy laws preventing them from calling people's cellular phones.
In addition, even if they wanted to call you, they can't find  your number because all cellular phone numbers are 'Unlisted' This is why you can't do it for "Free" Exactly.
You can't trace a mobile number for free.
If they're made available 'free', then it will become pretty difficult to protect mobile phone user privacy.
The chances are you will get a lot of calls from telemarketers etc.
There are too many services, which reverse phone service should I choose? There are many websites that charge you from $14.
99, $39, to $ 69.
But there are other companies that give you the same information for as little as 99 cents.
Most web services only provide you the name and address of the telephone owner.
(Sure they do give the cellular service carrier and the local region that the phone is registered to, but that information is not too valuable to most people).
However a few companies give you additional information like phone owner's relatives, associates, average income and average home value etc.
These can be important information to get an idea about the kind of person you are dealing with here.
