Hey guys,
Today I got an extra data card from my mobile carrier, but just adding a mobile broadband-connection in Network Manager didn't work:
mmcli getting status on the modem showed state: failed and reason: sim-missing. This happened both before and after I actually inserted the sim card:
sudo mmcli -m 0

Tried resetting the modem by running sudo mmcli -m 0 -r. First time, I received error message (error: couldn't reset the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Cancelled: AT command was cancelled'), then after retrying the command, it gave me a different error (error: couldn't find modem at '/org/freedesktop/ModemManager1/Modem/0'`)
Then I just tried the next modem in line (I saw in the folder tree that it had changed from 0 to 1):
sudo mmcli -m 1

SIM | dbus path: /org/freedesktop/ModemManager1/SIM/0
At least now it recognizes the sim card.
Then I try to connect through the sim card with nmcli:
nmcli d c cdc-wdm0 --ask
PIN code is needed for the mobile broadband device
PIN (gsm.pin): xxxx
Error: Timeout 90 sec expired.
In the meantime, I see that dmesg has been spammed with the following error: cdc_mbim 1-3:1.0: nonzero urb status received: -EPIPE
Just before these errors, it shows this:

How can I fix this error?
