<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a dual SIM IOT device which was running <a href="https://ubuntu.com/core/docs/networkmanager/configure-cellular-connections">modem-manager</a> 1.10 on Ubuntu 16.04. Recently upgraded to modem-manager 1.20.0 on Ubuntu 22.04.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When switching from the first slot to the second slot, modem-manager is stuck with 3GPP status "registered" with the warning messages<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><i><span style="background:yellow;mso-highlight:yellow">[modem0/bearer1] connection attempt #3 failed: Couldn't find associated QMI port for 'net/wwp0s29u1u1i10'</span><o:p></o:p></i></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don't think it is a slot/SIM/APN issue because it gets data connection if the device is rebooted with the 2nd slot active.<o:p></o:p></p>
<p class="MsoNormal">SIM switch from 2nd slot to 1st slot works fine so cannot be any issue with sim switch logic.<o:p></o:p></p>
<p class="MsoNormal">Any suggestion?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks and regards<o:p></o:p></p>
