GSM Board SIM900 NetLight and Status Light Unresponsive

Hello, I am new to the arduino community. Im a rookie arduinoer. But we just recently bought a GSM sled and it seemed to work the 2 times I used it the netLight and statusLight both flashed. Then the third time I tried it with a proper sim card in it. I have seen some youtube videos and everyone elses lights flash. We also have it hooked up to an arduino uno and there is no watch battery in it.

could anyone tell me what is happening?
