If you are a busy entrepreneur who always has to answer his or her cell phone then you can’t let your phone ringing without answering it. But in some situations you have to do that as your self esteem and privacy matters a lot. In some cases people call from an unknown number and after answering such calls we are forced to listen sexually explicit and immoral words that nobody wants to listen and even tolerate to hear. So now you want to check and find who called me and what the purpose of their call. Such questions will only be answered if you put some efforts to check and find out who called me.

In the past people used to get the services of private detective agents that are specifically paid for this sort of investigation. Ideally you provide them with a phone number of that person and some basic details like what was the time when that call was received and what exactly conversation took place. Private detectives are very good at this sort of investigation but the only problem lies in their rates as they charge huge amounts starting from hundred dollars per hour which an ordinary person cannot afford.

Online phone number directories are considered an important weapon to find out who called me. The reason of that is, on these directories every registered number is listed and basic info about its owner can be accessed easily. On the other hand, social and professional networking sites are of great importance as well because sometimes people have included their cell phone numbers in their public profiles so you need to put some extra effort in order to generate these details. Normally it is free of cost procedure as you just need to have an account on any of the sites.

Lastly you can use certain online databases that are specially designed to find out who called me. On these resources you just need to enter the phone number and pay some fee. Within no time they will give you the access to its results from where you can easily find out the name, address and other numbers being used by that person. These resources will charge you some fee ranging from $20 to $50 which is a reasonable amount and almost everyone can afford it.
