Introduction

4G Smart Phone Trainer is an ideal training equipment to teach the operation of 2G Dual SIM Mobile phone. The complete Block of Mobile Phone is printed on single PCB for easy understanding of function of different blocks. Test points allow the analysis and monitoring of the signals in different sections. By using the fault simulation method, it is possible to introduce the most common breakdown and their rectification.
