Hey,
while trying to resolve the issue when sending SMS with specific mbim
modems
(https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/562),
I see different behaviour when sending SMS depending on the modem I use:
* When I send an SMS using a non-MBIM modem (UBlox Toby L210, RNDIS),
the SMS is shown (using mmcli) as sent. When I then restart
ModemManager, the SMS is no longer there. So it seems that the
message is not stored in SIM or modem.
* When I send an SMS using my MBIM modem (Telit LE910C1-EU), the SMS
is shown (using mmcli) as sent. When I then restart ModemManager,
the SMS is still there. So it seems that the message is stored
immediately when sending (to be precise: Any attempt to send the SMS
creates an entry in the SMS storage on this modem -- so when I have
three attempts to send an SMS, two failed and the third succeeded, I
have two drafts and on sent message in the storage (!?) )
Is ModemManager capable to handle both of these scenarios? It seems to
me that ModemManager does not expect the second scenario, which leads to
the issue when deleting messages...
(BTW: In both cases, ModemManager crashes when I try to store the
message using mmcli after it has been sent).
