AT^BAND_PREF returns ERROR on MV31-W modem | Telit Cinterion IoT Developer Community

I have been trying out sending AT commands to MV31-W modem. Most commands are working, however I am unable to enable/disable bands using AT^BAND_PREF.
Here are some of my outputs :
at OK at+cpin? +CPIN: SIM PIN OK at+cpin=**** OK at+cfun? +CFUN: 1 OK at^slmode? ^SLMODE:1,4 OK at+cgdcont? +CGDCONT: 1,"IPV4V6","internet","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0 OK at^band_pref? ERROR at^band_pref=nr5g,2,71 ERROR at+cops? +COPS: 0 OK at+cops=1,2,"20815" OK +cops: 1,2,"20815",2 OK
I was wondering if the version we are using might have to be updated...
Here is the version of our MV31-W module :
at+skuid HW Revision : V065 SW Revision : T99W175.F0.0.0.3.4.GC.003 OK
Thank you in advance for your answer,

It is possible that your version does not support this command. It wasn't supported in some older versions yet. Your firmware is not new. I think that you need to contact your technical sales person of supplier for the firmware update.
In case it helps as a reference: works for me with this firmware:
HW Revision: V065
SW Revision: T99W175.T188.8.131.52.8.GC.004
