How to control servo motor with handphone through GSM modem?

[skimask]

I am currently doing a mini project of controlling the servo motor using easypic4.
I managed to control the direction the servo turns by using the pushbuttons on the board to make it turn clockwise or counter-clockwise.
However, I would like to control the servo by sending a message using handphone to the GSM modem which is connected to the RS232 com port of the easypic4 and make the servo turns accordingly.
What are the additional codes which I need to control using handphone?

Wow.........

I could say a lot of additional code...

In this special category on GSM there are many examples... Just search through. I warn you it is not an easy project...
