<p>Hi, <br>
</p>
<p>I am not sure, but I think that this is a problem with the UBlox
modems I was facing before with a TOBY 210. <br>
</p>
<p>The problem is that the modem does an automatic registration on
the LTE network using its default APN (that it gets from the
network, when I understand right). That is what you see
(m2m.com.attz.mnc170.mcc310.gprs) as context 4: (which is the
default LTE bearer on TOBY). Unfortunately, that does not match
the one your have given manually, so ModemManager tries to build
up a connection using the secondary context with the APN settings
you have given -- which fails, because the service provider does
not allow a secondary connection while the first one is active. <br>
</p>
<p>What I am not completely clear about is, under which
circumstances you get such a long default APN name (not matching
the 'official' ones) from the network. <br>
</p>
<p>@Aleksander: See <a
href="https://lists.freedesktop.org/archives/modemmanager-devel/2018-August/006633.html">https://lists.freedesktop.org/archives/modemmanager-devel/2018-August/006633.html</a></p>
<p>I heavily change the ublox plugin to work around that --
unfortunately I never found the time to bring it to a deliverable
state, and at the moment, I can't even remember what exactly I
did. But I can provide the sources if needed.... <br>
</p>
<p>Best regards, <br>
</p>
<p> Uli</p>

You need to setup ModemManager running with --debug so that we
can<br>
look at the debug logs produced, we need to know which
specific AT<br>
command was the one failing and triggering the simple connect
error.<br>
