How do I get the Itead 3G shield to work?

I’ve tried a pretty standard code but the Serial Monitor yields zero response.
Using a standard Arduino Uno (tried a second one as well, just to be sure) and am now trying the second shield with this code:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

void setup()
  Serial. begin(9600);


void loop() // run over and over
  if (mySerial.available())
  if (Serial.available())

There is nothing coming back whatsoever in the serial monitor (yep, I checked the baud rate and tried several others).

Any ideas?

What should I be seeing if anything?
