I’m trying to set up an LTE hat with a Telit LE910C4 module ans a Vodafone SIM on my Raspberry Pi 4.
I followed this tutorial to set up a QMI based connection. Every step in the tutorial worked until I tried to connect.
pi@raspberrypi:~ $ sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net=‘net-raw-ip|net-no-qos-header’ --wds-start-network=“apn=‘web.vodafone.de’,ip-type=4” --client-no-release-cid
error: couldn’t start network: QMI protocol error (14): ‘CallFailed’
call end reason (3): generic-no-service
verbose call end reason (3,2007): [cm] (null)
[/dev/cdc-wdm0] Client ID not released:
Service: ‘wds’
CID: ‘19’
Username and password are not needed. Vodafone germany uses two different APN’s for their SIM cards: web.vodafone.de and event.vodafone.de. Mine should be the first one, but I tried both with the same result. Also, entering complete nonsense for the APN yields the same result, so it’s problably not the credentials.
As the part generic in the error name says, it’s a pretty generic error description that doesn’t tell me anything about it’s cause.
Following, I’ll post what I think is important. If I’m missing anything, let me know.

I’m pretty sure, the AT+CGDCONT? command shouldn’t yield ERROR, right? However, I can’t deduce any solution from that.
