MBIM on EC25-AU

Hello,

I am attempting to switch an EC25-AU module from UART/PPP mode 0 to MBIM mode using the AT command AT+QCFG="usbnet",2 and it is not taking effect. Is there a firmware update needed for this module to use MBIM?

The currently installed firmware is EC25AUFAR06A05M4GA

Thank you,
Rayne
