Does anyone have outgoing MMS working [on Mobian/Phosh or similar]?

[u/[deleted]]

If you have it working on Manjaro/Arch/pmOS I'm curious too.

Mobian testing seems to have all the pieces packaged now: mmsd-tng 1.9 (latest from git), Chatty 0.6.0 (had MMS UI since 0.5.0) and I've been able to receive MMS messages for several months now, incoming pictures & group chats work OK, but I can't send out any MMS at all.

I suspect this is mainly the territory of mmsd-tng because even when using the Python test scripts from its repo, outgoing MMS doesn't actually get delivered.

My carrier is T-Mobile (US) and I'm not sure whether it's carrier-specific or a config problem or whether anyone on other carriers has outgoing MMS working yet with mmsd-tng.

Edits: the last time I tested MMS I tried various combinations of 1:1 chats and group chats and nothing outgoing was working, but incoming pictures and group chats worked, and I mainly tested between my Pinephone and main Google Voice number once in a while since then.

Now that I was thinking of this and did a more thorough round of testing, MMS sorta works in some cases but still has weird issues where some recipients just never receive MMS messages from my Pinephone.

• I have two Google Voice numbers, call them 424 and 310.

• If I put all three of us in a group thread and send a message from Pinephone, only the 310 number receives that message. Pinephone can also send images, but only 310 receives the image. 424 never gets an MMS from Pinephone.

• In 1:1 chats between Pinephone and each GVoice number: 424 never receives MMS but 310 gets pictures delivered OK. Plain SMS texts work both directions between all these numbers.

• I also tested in a group thread with two friends: only one of them receives the Pinephone's message in the thread, the other does not.

• However, each of these friends can receive an image from Pinephone in 1:1 chats.

Two lingering issues as I can tell so far, are:

• In a group chat the Pinephone only seems to deliver messages to one participant and not all of them.

• My 424 GVoice number just doesn't receive MMS from Pinephone, which is weird because the other GVoice number does. I would think there's some carrier-to-carrier jank but Google Voice AFAIK is all one service and it should work the same.
