<!-- Hello, Please keep in mind that one person is essentially "at the helm" for this project. When you file an issue, I have to directly respond to it, and I am maintaining this in my spare time. I will close issues that are duplicates, already solved, or not bugs in mmsd-tng; and reserve the right to close it with a vague message (since hunting down references takes up time that could be spent working on mmsd-tng). If you aren't sure about the issue (or I closed it with a vague message), please ask on the "Open Source MMS/VVM/Other Wacky Telepathy Standards" Matrix/IRC Channel (They are the same channel), as you will likely be helped faster this way (since many knowledgeable people are on this channel): #opensourcemms:matrix.org #opensourcemms on OFTC IRC Chat If you are sure there is an issue/bug in mmsd-tng, and it is not a duplicate/already solved, please use the below steps to describe the behavior, in doing so will make it easier for me to help with the issue/bug (Not having this will make me either ask for it, or just make me close the issue since I cannot help): --> ## Summary <!-- (Summarize the bug encountered concisely) --> With mmsd-tng 2.6.0-3 and modemmanager 1.22.0-3+b1 on a Mobian/trixie PinePhone v1.2b and manually switching from my mobile provider's 'Internet' APN to its 'MMS' APN, I can send MMSes successfully, but I cannot fully receive them. Journalctl logs suggest that the message is received, but suggests that it was not decoded correctly. ## Steps to reproduce <!-- (How one can reproduce the issue - this is very important) --> ```` $ sudo systemctl stop ModemManager.service $ nmcli conn show |grep gsm Internet UUID1-UUID1-UUID1-UUID1-UUID1-UUID1 gsm -- MMS UUID2-UUID2-UUID2-UUID2-UUID2-UUID2 gsm -- $ systemctl --user stop mmsd-tng.service $ sudo systemctl start ModemManager.service $ systemctl --user start mmsd-tng.service $ nmcli conn show |grep gsm Internet UUID1-UUID1-UUID1-UUID1-UUID1-UUID1 gsm -- MMS UUID2-UUID2-UUID2-UUID2-UUID2-UUID2 gsm -- $ nmcli d |grep MMS cdc-wdm0 gsm connected MMS $ nmcli conn show |grep gsm MMS UUID2-UUID2-UUID2-UUID2-UUID2-UUID2 gsm cdc-wdm0 Internet UUID1-UUID1-UUID1-UUID1-UUID1-UUID1 gsm -- ```` * A person with another phone sends me an MMS. ## Carrier Settings <!-- What Carrier, APN, MMSC, and MMS Proxy are you using?
