Step 1: set GPRS Commands(ie APN) of SIM900

Step 2: set tcp ip connection to your static server and port number(AT command is given in manual. static IP is must)

step 3: When TCP/IP connection gets ready, send command from server(use Hercules software) to your device to on/off led.

step 4: read server's command from your arduino and make led on/off.

I hope it help.
