Hi,
I’m trying to perform VoLTE calls in Italy using a QUECTEL EM12-G both with Vodafone and TIM operators.
The problem is that It seems that in the MBN files present these operators do not appear for the VoLTE.
Is it possible to have a MBN file for such operators and for the other italian plmn?
If this is not possible, is there a way we can forge one by scratch?
Thank you for your response.
I managed to solve the problem with TIM operator by using the following steps:
AT+QCFG="ims",1
AT+CFUN=1,1 (then wait for the settings to be applied and the EM12-G to be rebooted)
then
AT+QMBNCFG="SELECT","ROW_Generic_3GPP"
AT+QMBNCFG="autosel",0
AT+QCFG="ims",1
At this point I was able to perform VoLTE calls.
The same unfortunately did not happen for Vodafone, which i think it means that the MBN file “ROW_Generic_3GPP” does not include Vodafone plmn.
Can you verigy that with the R&D team if possible?
