led on through sms using gsm shield sim900?

can anyone send me code how to turn on/off led using gsm shield sim900???

You want to use a shield to turn an LED on and off? The simplest, then, is to glue the shield to the end of a servo, and position it over a switch. Rotate the servo to one position to turn the LED on, and to another position to turn it off.

That could work, although I haven't tried it myself.
