<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hey, while trying to resolve the issue when sending SMS with specific mbim modems (<a class="moz-txt-link-freetext" href="https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/562">https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/562</a>), I see different behaviour when sending SMS depending on the modem I use: <ul> <li>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. </li> <li>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 (!?) ) </li> </ul> 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). <pre class="moz-signature" cols="72">-- Best regards / Mit freundlichen Grüßen / Salutations distinguées Ulrich Mohr SEMEX-EngCon GmbH Carl-Merz-Strass 26 76275 Ettlingen Phone: +49 (0) 7243 5143596 email: <a class="moz-txt-link-abbreviated" href="mailto:u.mohr@semex-engcon.com">u.mohr@semex-engcon.com</a> ___________________________________________ Executive board: A.
