Hi all,
I have the Icomsat v1.1 GSM shield (http://imall.iteadstudio.com/im120417009.html) also using the library provided by them (ftp://imall.iteadstudio.com/IM120417009_IComSat/Lib_GSM_Shield.zip).
I have been able to send SMS with a different library using AT command. But AT commands are not my strong point so I want to use the original library instead.
Im trying to run a simple sketch to show if im connected to the network. But can't get it to work.
Ons my shield I have put the jumpers to use TX(3) and RX(4) as this is what the Library requires but I am not sure if I did it correctly.
I have attached an image of my shield with the jumpers set:
Here is my example sketch followed by the results from the Serial Monitor.
Any advice or help would be appreciated
Thank you 
#include <SoftwareSerial.h>
#include <GSM_Shield.h>
GSM gsm;
void setup() {
Serial.begin(9600);
Serial.println("system startup");
gsm.TurnOn(9600);
gsm.InitParam(PARAM_SET_1);
gsm.Echo(1);
}
void loop()
{
int reg;
reg=gsm.CheckRegistration();
switch (reg){
case REG_NOT_REGISTERED:
Serial.println("not registered");
break;
case REG_REGISTERED:
Serial.println("GSM module is registered");
break;
case REG_NO_RESPONSE:
Serial.println("GSM doesn't response");
break;
case REG_COMM_LINE_BUSY:
Serial.println("comm line is not free");
break;
}
delay(2000);
reg=gsm.IsRegistered();
Serial.print("Registration ");
Serial.println(reg);
delay(50000);
}
And here is my Serial Monitor output
system startup
GSM doesn't response
Registration 0
