Following the instructions, everything seems to compile and install. To test, I directed two MMS messages with image attachment to the PP from an AT&T device. Here's what happened:

-The SMS quickly came in as expected and appeared under the AT&T inbound phone #.
-A reference to the MMS attachment appeared quickly, but appeared under a seemingly arbitrary inbound #.
-The MMS entries in Chatty all display the text "plication/vnd.wrap.mms-message" rather than the file information in your screen shot.

Also, I removed the Chatty auto-run entry and launched manually as described in the instructions (but have not built from sources). Interestingly, after exiting Chatty for a bit and re-running, Chatty detected both test messages for a second time and downloaded them again.

What is the source repo location?

Quote:It would be great to integrate it into mobile-broadband-provider-info  ( [https://gitlab.gnome.org/GNOME/mobile-br...vider-info), and provide a way to provide a setting to provide the MMSC settings.

Bearing in mind I've never encountered an .XSL document before and am not at all sure how these pieces fit together, I did some poking around and the fields we need appear to have already been integrated/implemented.

There is a conditional in apns-conf.xsl on the usage field of an APN entry (provider>gsm>apn). When usage is set to "mms", the logic integrates the mmsc and mmsproxy fields. The mmsproxy field is parsed to derive mmsport (from mmsproxy:port, or default to 8080).

In serviceproviders.xml, many of the carriers already have MMS apn entries defined, which appear include needed fields to set up the internet connection. I don't see obvious changes needed at this level. It looks like everything is there.
So If you can, please download a later version of purple-mm-sms. What is going on is that when you get an MMS, it first downloads what is called an "SMS WAP". This is a notification to go to a link and download the actual payload. I made that a bit clearer in a newer version of purple-mm-sms (and i cleaned upquite a bit of the code too):

https://source.puri.sm/kop316/purple-mm-sms/-/tree/mmsd

Also, are you running mmsd?

And the repo for chatty is:

https://source.puri.sm/Librem5/chatty

without a more detailed log of mmsd or chatty, I am not sure i can help?
