When connected to 4G no UK network will accept telephone calls.
I’ve tried EE, O2 and Vodafone.

AT+QCFG=“ims” always returns:
+QCFG: “ims”,1,0
Does this module support VoLTE? Currently all calls are on 2G/3G

1:Does the SIM card you use support the volte function?
2:Whether MBN is activated
AT+QMBNCFG=“list” +QMBNCFG: “List”,0,1,1,“hVoLTE-Verizon”
The first 1 means it has been selected; the second 1 means it has been activated;
You can use the command: AT+QMBNCFG=“select”,“hVoLTE-Verizon” to select the required MBN; when the MBN is selected, use AT+CFUN=1,1 to restart the device and the MBN will be activated
