MMS sending stopped working

[amindfv]

I've been mostly-happily using the PinePhone with Mobian for a long while (years), with MMS working pretty smoothly for a long time. Recently (last 5 days or so), MMS sending has completely stopped working.

  - It didn't happen after making any big software change (apt upgrade, settings change, things like that).
  - Group message sending and 1-on-1 media sending no longer works
  - Group and media receiving still works totally fine
  - Back when MMS sending was working, I noticed that after hitting "send" on an MMS message, the screen brightness would always change for a moment (something to do with power draw to the antenna?). Now when I try to send MMS that doesn't happen.

Any idea what the problem could be?

If it did work before most likely your carrier change something. I am quite sure that because of some carrier changes kop316 need to do some changes (not affecting to me so can't confirm and this comes from my memory so might be wrong).

What you can do is try to upgrade and see what happens?
MMS is complicated and the biggest problem is almost always your carrier (not your own OS or mmsd-tng)

There was a recent update to mmsd-tng (v2.1.0) to fix a problem that came up with T-Mobile.

It could be a modem or carrier-side issue, especially since you didn’t change anything on your phone. Try rebooting the modem (mmcli -m 0 --reset) or reseating the SIM card; if that doesn’t help, check APN settings for MMS or contact your carrier.

Probably not important but in Mobian the MMS settings has a place for the modem's phone number, what is this all about? I have never seen anything in another mobile running Maemo, android, or v60 having this entry.
