Thanks for the reply. I did email them but that didn't produce any new information.
I did manage to send a few mms messages on a fresh Manjaro Phosh install, but I haven't successfully received any yet. Unfortunately, sending messages is broken again also. Not sure what caused that, unless the unread messages are somehow blocking the send process.
Looking around at the mmsdtng -d output, I see the following "repeated" several times (the data change, but the pattern is consistent):

An http 503 error seems problematic. It seems to connect, but then the server says it is unavailable, so I don't know what to make of it. Has anyone else tackled this problem?
Thanks again.
