Wire up the sim holder to uC port.
Wire up the GSM hardware to the uC port.
Wire the keypad to uC
Write the code for the uC
Oh wait I forgot. Wire up the LCD to uC port.
Again write the code to display data in LCD.

Insert SIM with proper carrier.
Put some money in the SIM .

Then send the SMS.

Isn't that simple.

Answer is simple.
We do not write codes and give them away.
You have to write and show us then we can correct them

And hijacking thread is a NO NO !
