<br>
Is this device relatively new? What is the "vid:pid" of the device?<br>
Could you get a full "lsusb -v" output of the device?<br>
<br>
I see the modem is exposing multiple AT and net ports, but<br>
unfortunately ModemManager doesn't know how to handle those net ports,<br>
so if you get that modem connected it will be using PPP over a TTY,<br>
which is not optimal. The connection and management will work, but it<br>
won't be as good as it can be,<br>

<br>
The rule files are "helpers" really, there is no need for the rule<br>
files usually. In your case, I believe the modem isn't using any of<br>
the rule files that ModemManager provides.<br>
<br>

<br>
As in the previous email, you probably don't need username, password,<br>
and lowpower. And you only need pincode if your SIM card is<br>
PIN-locked, which may not be.<br>
<br>
Cheers!<br>
