It doesn't connect. The journal has these messages repeated several times:

<info>  Simple connect started...
<info>  Simple connect state (4/8): Wait to get fully enabled
<info>  Simple connect state (5/8): Register
[/dev/cdc-wdm0] No transaction matched in received message

I tried both with a data-only SIM from R and a standard mobile phone SIM
from Movistar. I don't think it's related to the SIM card. Could it be a
problem with the driver? I also noticed these lines earlier in the journal:

<warn>  couldn't load IMSI: 'Couldn't get UIM IMSI: QMI protocol error
(37): 'UimUninitialized''
<warn>  couldn't load Operator identifier: 'Couldn't get home network: QMI
protocol error (37): 'UimUninitialized''
<warn>  couldn't load Operator name: 'Couldn't get home network: QMI
protocol error (37): 'UimUninitialized''
<warn>  couldn't load list of Own Numbers: 'Couldn't get MSISDN: QMI
protocol error (37): 'UimUninitialized''
