Pak Sim Data is an application that allows users to find the details of a person who is calling or texting them. This is a very simple and easy-to-use application, which provides the user with a list of all the numbers that have been registered on the SIM card of the device. The user can select any number from the list and get all the details, which include the name of the owner, the address, and the date of birth. 

This application can be very useful to the users, because most of the time, they don't know the number of their device, and if they do, it is very difficult to remember the number and the name of the owner.
