SIM 300 is a widely used module. You should learn AT commands to control the module before start coding. 

Try making call, sending message etc. by sending AT commands through hyperterminal to the module. If it works, then your code running on the microcontroller should be capable of sending the same commands serially to the module. 

Feel free to ask more doubts. Good luck with your project.
