How to enable the VoLTE on BG96

Hi,
We are trying to enable the VoLTE function of BG96 in Japan. However, we’ve not been able to activate and test the function. Please let us know the right way to start its function.

We tried the procedure below.

16:38:22.390 → AT+QMBNCFG=“list”

16:38:22.390 → +QMBNCFG: “list”,0,0,0,“Softbank_Commercial”,0x0581C805,202012191
16:38:22.390 → +QMBNCFG: “list”,1,0,0,“Netherlands_Vodafoneziggo_volte”,0x05815802,202012191
16:38:22.390 → +QMBNCFG: “list”,2,1,1,“ROW_Commercial”,0x05010804,202101041
16:38:22.390 →
16:38:22.390 → OK

16:41:10.137 → AT+QMBNCFG=“select”,“ROW_Commercial”

16:41:10.551 → OK

16:43:56.713 → AT+QCFG=“ims”,1

16:43:56.713 → OK

16:44:55.788 → AT+CFUN=1,1

16:44:55.788 → OK
16:44:55.788 →
16:44:55.788 → +QIURC: “pdpdeact”,1 // Forgot cutting network
16:45:02.437 →
16:45:02.437 → RDY
16:45:02.789 →
16:45:02.789 → APP RDY // Done reboot

16:46:53.901 → ATD00000000000; // tried to call

16:46:53.901 → ERROR // Failed to call

16:47:17.824 → AT+COPS? // confirmed wheather it has been conntected or not

16:47:17.824 → +COPS: 1,0,“NTT DOCOMO NTT DOCOMO”,8
16:47:17.824 →
16:47:17.824 → OK


In addition, We confirmed that the SIM is compatible with VoLTE.

Hi Kentaro,

Could you please help check AT+QCFG=“ism” return value?

Hi, Linkin-Q,
Possibly, here
“ims” instead of “ism”
it might be.

By the way, ERROR is returned with “ism”.
For ims, +QCFG: “ims”,1,0 is returned.
Here is the result.

Hi,

As the return we can see:
the second parameter 0 means: VoLTE not ready.

So, could you please check this?

Thank you for your kind reply
Would you let me know what manual and where of it describes how to enable it?
