I just have one question, Is this CSIM command supported in all telit Modems? It wouldn't be good if by implementing this change on telit-plugin to fix this issue on telit HE910 and the other modems that can use this command, other modems stop working.

But all the other intermediate steps never fail; i.e. csim_query_ready() always goes to the next step, never completes the GSimpleAsyncResult. So effectively, if any intermediate AT command fails, we just go on to the next one, and after the last one we have the CSIM=0 to unlock. -- Aleksander <a href="https://aleksander.es" rel="noreferrer" class="gmail_msg" target="_blank">https://aleksander.es</a> </blockquote></div>
