EG25-G is USSD possible?

Hello. Is the EG25-G module capable for USSD? I have upgraded the module to the latest firmware version and I’m unable, yet, to use USSD queries. The AT command in using (I’m my case to check data balance is *121#) is:
AT+CUSD=1,"*121#",15
Just getting an OK as an answer but nothing more.
Additionally, the module can received SMS but I’m not able to send any.
Thanks in advance for your support.

Hi,you can run the AT+QCFG=“ims/ut” command to check whether the USSD is enabled. If the third digit is 0, it indicates that the USSD is disabled and needs to be set to 1.

I have the same problem with AT+CUSD not working on an EG25-5. I’ve tried several different versions of the firmware. However, none of them I’ve tried have the AT+QCFG=“ims/ut” function. Currently I’m using this firmware:
EG25GGBR07A08M2G_01.003.01.003
I’ve also tried EG25GGBR07A08M2G_30.007.30.007 without success.

This seems like a pretty basic function to not have working in the latest firmware. Is there something I’m missing?
