Can't connect to file server through Samba without SIM card?

Hi all,

I have an E750 that I am running without a SIM card. Just using it as a portable Wi-Fi repeater. I’m unable to connect to the file server from either Windows or iOS. Each time I connect, the following error shows up in syslog:

Sat Dec 10 21:53:36 2022 user.debug : MCU SIM ERROR

Seems odd this would be related to the Samba server. But it appears to be (this error happens each time I try to connect). Any idea how I can work around this? Is there a way to completely disable the cellular services?

Thanks!

This message may not relate to your file server.

Should be just a SAMBA version issue I think.
