help troubleshooting sim7600 modem on raspberry pi
Budget: £10 – £20 GBP
I have set up a sim7600 modem on a Raspberry Pi 4 following this tutorial https://www.hannahtech.co/post/raspberry-pi-sim7600g-h-4g-hat-modem-setup
Unfortunately when I try to connect the modem to the phone network I get this error:
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: '17'
