I was unable to make a voice call with the RM520NGLAAR01A08M4G? Never on 3G, LTE and 5G network. Is this feature available on this version ?

The R520N-GL is designed for data only. And it do not support the voice call.
Quectel won’t open the feature for it even later.
If you must try it, you can try
AT+QCALLCFG=“voice_disable”,2
But it is not recommended. If you need the voice call feature, it is better to contact with the sales for another Quectel modem.
