GSM Reset is connected to pin 4, and GSM On/Off is connected to pin 5, of the Arduino.

Are those input 4 and input 5, they dont seem to be IC pin numbers.

Shutting itself down? I have thought that it just goes crazy. How do you check power state. What AT commands. Or is it so that when there is no response to the AT command, the shield is down.
Interesting ideas. Thanks.

Unfortunately they used the POWERMON pin for voltage level translation so you can't monitor that.  You could use the function CheckRegistration() as one of the returned values is  NO RESPONSE.  Another thing you can try is configuring one of the GPIO's as an output and wiring it to one of the MEGA's digital pins.  If the unit shuts down the pin will probably go to some tri-state state (you'll need to read over the data sheet).

They are not IC pin numbers. They are Arduino (digital) pin numbers.
