I have the same problem with Orange (Poland) - after a day I get a message, that MMS hasn't been received. However, I don't have this issue with another provider - Play (Poland).

It could be that the ACK message isn't sent properly (or maybe ACK is disabled in config) leading the carrier to believe that it was never received.

It was indeed disabled. I'm activating them, and will keep the ticket up to date. Thank you!

According to this website:

• MCC for Poland is 260 and MNC for Orange is 05 or 03.
• MCC for France is 208 and MNC for Bouygues Telecom is 20, 21, or 88.

MMS configs for these providers is either missing or outdated in android-smsmms (used by this app).

Updating the MMS configs should solve this issue, perhaps using a workflow for periodic updates.

As a note, on many carriers the AOSP ones don't fully work either -- only the newer Google messages mms configs.
