Dragino Nb IoT BG96

Hi everyone!
I’m having trouble setting up the Dragino NB-IOT BG96 with Hologram Simcard from Australia. I went through their document but it seems to be outdated and I couldn’t get it up running. I ran their sample code, tried the AT command and such but there was nothing in return. Has anyone got any experience with this module before? I’m paring it with the Arduino Uno v3.
I have activated the sim but so far, I have not yet seen it connect to a local tower or pass data.
Any suggestion for connecting it to the network would be highly appreciated!
