Nowadays communication is a crucial part of our daily lives and mobile phones are the primary means of communications in the Philippines. Being able to communicate with other people is no longer enough, the communication experience must be satisfying through minimal to no errors in the products such as SIM cards and cellular phones, and services such as accepting calls, receiving text messages, sharing of load, etc. This project is made to create an automated stand-alone microcontroller-based embedded testing system that will replace the current manual testing system used by SMS Global Technologies, Inc. The group does not eliminate human participation in the testing process, but minimizes the chance of human error from occurring by designing the microcontroller program to have the GSM modems perform tests on SIM cards which is once instructed by the microcontroller, record the results, and export it to an MS Excel file. The project dealt with checking of SIM card functionality such as balance checking, reloading, texting, calling, subscribing to GCASH, etc. This paper also includes complete discussion on different hardware components used , microcontroller programming, database programming using MySQL, GUI designing via Java, and both overall and detailed design of the project.
