Request to Enable IMS-SMS for LGU+ MBN

IoT Modules LTE Standard Module
1

Hello,

On the Commercial-LGU MBN profile for EC25/EG25, SMS fails on LTE-only LGU+ network because IMS-SMS is disabled.

Please provide an updated MBN or firmware that enables IMS-SMS or allows AT+QIMSCFG=“smsdomain” to configure it.

This is essential for SMS on LGU+ where no CS domain exists.

Thank you.

My firmware: EC25EFAR08A05M4G_KR_01.001.01.001

Hi,
Sorry for the delayed response.
I have sent you a version of the IMS that supports LGU+ operator privately. You can test it first.
