EG91 VoLTE UK Networks

When connected to 4G no UK network will accept telephone calls.

I’ve tried EE, O2 and Vodafone.

EG91EFBR06A06M4G

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
