Hi all, I can't get MMS working on my device using Mint in the US.

I set my APN and MMSC in chatty and mobile network settings according to: https://www.mintmobile.com/help/how-to-configure-android-settings/

Every time I send an MMS using the built-in mmsd, the following happens:

- No image shows in the Chatty message log after hitting Send
- No MMS is sent to the target device
- mmsd CPU usage shoots up to 100%
- mmsd logs continually prints the following at rapid speed until mmsd is killed:

1736379108.29728 OfonoMMSServiceInterface(/ril_0).send_message: Error sending message: [Errno 111] Connection refused. Retrying...

I did also catch this in the logs when testing (seems separate from the connection issue, but the cause of the 100% cpu usage):

/usr/lib/mmsd/mmsd/ofono_mms_service.py:147: RuntimeWarning: coroutine 'sleep' was never awaited
  asyncio.sleep(5)

mmsd also reverts the APN to incorrect settings on launch - it uses Ting mobile's APN (wireless.dish.com), not Mint's (wholesale) as configured in the system settings.

I have confirmed that I can access the internet and MMSC server from the device over 4G.

Device is fully updated with today's updates. Not sure where to go from here. Any insight would be appreciated.
