Modem SMS issue(s)

[StephanM]

There could be two separate things possibly going on:

1. Older chatty versions (the SMS UI) will delete your mmcli SMS due to a bug before you get to send it. Either upgrading chatty, or making sure it doesn't run in the background even when the SMS UI is closed (which it usually does) via "killall chatty" should help for these disappearing SMS.

2. There seems to be a compatibility issue with the modem and some phone operators leading to a temporary delivery failure reported by the phone network. I got that too, I can only receive SMS. I've been emailing the ModemManager dev with logs, so far it does appear to be unclear what the cause is. So if you always get timeouts sending, maybe this could be the same problem? Just a guess.

I receive the same error message:

Code:

error: couldn't find SMS at '/org/freedesktop/ModemManager1/SMS/4':
'not found in any modem'

I tried the approach of @jabadahut91 and the Chatty killall command. It did not help

I am using the pinephone ubuntu touch version by the way. As the status of the modem seems to be okay I feel like I do not have the same problems as you.
How can I find out if I have the same problem? Should I report the problem to https://gitlab.freedesktop.org/mobile-br...demManager? Do you know if I can provide further information?

Thank you so much
