My experience is that turning off mobile data also prevents mms from incoming. Those who receive mms may not want to do this as they donā€™t tend to control when messages will be sent to them.

Yes this is correct, if you turn off data you will not get any MMS messages.

I have in the past couple days just been toggling the mobile connection off then on after aquiring a new wifi connection to see how that works. I also have tcpdump running in a terminal window that I periodically clear just to see if there is an over abundance of activity on the interface.

Itā€™s worth noting that MMS not being delivered with mobile data off is just a shortcoming of the current implementation and itā€™s not going to stay this way in the future.

That would be a hugely welcome change from my perspective, at least for working around problems like this.

Just wanted to point out that this bug seems to have been fixed with the kernel update the week of 10/23. Now PureOS switches from mobile network to using WiFi without any fuss. At least thatā€™s what Iā€™ve observed this last week.
