</div></div>You need to check the *bearer* object in DBus to know the connection<br>
details, once connected.<br>
<br>
You can check the list of available bearers with:<br>
$ mmcli --list-bearers<br>
<br>
And once you know which one to check, you can query its info, e.g.:<br>
$ mmcli -b 0<br>
<br>
That will tell you which IP method to use (ppp, dhcp, static) and all<br>
the other info.<br>
<br>
Also, when you run --simple-connect you should get as output which of<br>
the bearers just got connected.<br>
