Hello, I’m using a Quectel EC25 module to connect to cellular using my SixFab simcard. The module is connected to raspberry pi 4 b. The core device is shown active on my dashboard, my simcard is active. My APN is set to super and I have set the fleet to unlimited data. But I do not know why I can not connect to cellular network. Here is a sample output of some AT commands.
