The Different Possible Procedures to Block the entire Problem Premium numbers in the Network is projected. In paper we also discussed Mobile Computing Architecture and different data mining techniques that are used to collect data, demonstrating how the frauds will be predicated and various fraud detection techniques are discussed. The Design and implementation of a software tool is described along with the tool architecture and how the inner workings are interrelated. The conclusion is given for the Prevention and Protection with Experimental Results and Graphical Analysis of Tool Performance.
