I quote myself here:

Well cellular data is necessary to send/receive the MMS, see for example: https://forum.telus.com/t5/Mobility-Services/Why-do-I-need-Cellular-Data-turned-on-to-send-receive-MMS/td-p/39622
Please also read this https://en.wikipedia.org/wiki/Multimedia_Messaging_Service fully to understand the service.

That means, technically it is not possible to receive an MMS without mobile data. But of course there should be an SMS notifications, but this could be provider dependent.

With devel channel updates as of 2021-12-17 I can confirm this is fixed. I disabled cellular data and wifi and sent a photo MMS to UT. I got the message that there was a new MMS with the filesize and a download link. I then enabled cellular data and clicked "Download" link and image was delivered.
