EG25G Serial (Not IMEI) number via AT command

Is there an AT command to get the Serial Number (Same as etched on the module) of an EG-25?
I know about the AT+CGSN command which gives me the IMEI. This is not what I want.
I want the SN that is etched on the module above it.

Many thanks,
Ken

Hi, is there an AT command to restore the IMEI and SN# to default for an RM502Q-AE ?
Seems strange I would have to reinstall the firmware to fix this issue.
