Hi,
From the logs I see that the signal quality is pretty poor, could you try putting your router in a more open space?
Check if your antennas are attached correctly and your power cable is not broken as it could not give enough power for the modem to work properly.
Also, I see that there's message spam of AT+CPIN, which means that there's a pin requirement enabled on the SIM card, could it be that the PIN is entered wrong or is not entered at all?
