        Hello all,

        I recently changed mobile networks. Unfortunately, I can't seem to get any MMS messages to send - they show as sending for a few minutes and eventually fail.

        I suspect the problem might be with the APN settings - my current mobile network is Superdrug Mobile, an MVNO using 3's network. The reason I mention this is that the SIM card's default settings are all labelled 3 and use the three.co.uk APN, apart from 3 Modem which uses 3internet, while my network gives these settings which use the superdrug.net APN - all the other settings are the same between this link and the default ones. Enabling only the MMS-only one and changing them all to example.com both have no impact on internet access, which still works. The changes show up in the APN settings but seem to have no impact outside of that.

          @ultrasonicnoise I found these
          Name: 3 Internet
          APN: three.co.uk
          Proxy: Not Required
          Port: Not Required
          Username: not required
          Password: not required
          Server: Not Required
          MMSC: http://mms.um.three.co.uk:10021/mmsc
          MMS proxy: mms.three.co.uk
          MMS port: 8799
          MCC: 234
          MNC: 20
          Authentication type: Not Required or just use the default value shown

          I use Plusnet and had to set up two connections for it to work using EE apn settings. One just for internet and one just for mms have you tried that not sure from your post.

            @lakotaubp I tried the given settings - the ones I could input (MCC and MNC are not present for me) and they still don't work.

            I strongly suspect the problem is that changing the settings has no actual impact on the relevant connections as setting the APN to example.com still allows me to connect to the Internet. Is there a way to check which APN Ubuntu and Nuntium are attempting to send the message over?

              @ultrasonicnoise sorry no idea on how to do that. All I do know is that the settings do matter and my plusnet ones have never been right without me adjusting them. As mentioned before I had to set upmtwo apn settings before for internet and mms now on FP4 they need to be together as mms settings stopped the mobile internet otherwise

                In my past experience (and more recently on a fresh 20.04 install), sometimes the UI is glitchy to accept and remember changes (you did reboot, right?) ... To overcome this, I had luck changing the file that feeds the default APN settings when you reset / delete them then reboot. The file is:

                /usr/share/mobile-broadband-provider-info/serviceproviders.xml

                To edit it, you will need to remount the / file system r/w ...

                I found my carrier ... then edited the section to reflect the proper APN entries ... then delete APN entries & reset (they were hard to get rid of) then reboot ... and it should pull in the new values from that file. Hope this helps!

                  @standupmobile I changed all mentions of a three.co.uk APN in this file to superdrug.net, deleted all MMS settings and reset them System Settings and it still reverts to three.co.uk on reboot and after multiple reboots.

                    Hmm ... so if that APN is no longer in the file, then maybe it is not matching the "3" in the name field and so it defaults to what the provider or sim card sets? (I am assuming that is what it uses to match ... ) Sorry, not sure what to suggest from here ... ??

                      <provider primary="true">
