We are conducting a test with a customer using HL7800 (F/W: 4.6.9) with MVNO USIM.
However, after downgrading to FW 4.4.20, the USIM is attached during the test, but it remains unattached in FW 4.6.9.
After examining the differences, we found that FW 4.6.9 includes the NB-IoT Stack (1), while FW 4.4.20 only enables CAT-M1 (0).

I want to disable NB-IoT Stack (1) in FW 4.6.9 and conduct a test using only CAT-M1 (0), as in FW 4.4.20. What AT command can I use to disable it? Or, is there a way to use only CAT-M1?
plz give a feedback..
thank you
