Dlink DWM-222 - QMI "callFailed"

Installing and Using OpenWrt Network and Wireless Configuration
1

So I have a TP-Link travel router that I used to use in my car with a Dlink DWM-222 USB LTE stick. This used to work fine but I decided to stop using it and it has sat powered off for about 1 year now.

Now I want to implement this setup again, but now I cannot get the LTE connected again. When attempting to connect to the network I get the following 2 errors (at random)

  • "CallFailed"
  • "No effect"

I have confirmed my device is registered.

uqmi -d /dev/cdc-wdm0 --get-serving-system

And that it has a good signal

uqmi -d /dev/cdc-wdm0 --get-signal-info

But still, I cannot connect with

uqmi -d /dev/cdc-wdm0 --start-network internet --autoconnect or uqmi -d /dev/cdc-wdm0 --start-network vodafone --autoconnect

I am a little lost as the device is connected to the network, shows as registered and I am 100% using the correct APN, still cannot open a connection.

Any ideas?

Thanks

Show the output of cat /sys/kernel/debug/usb/devices
Show the modem interface configuration, just the relevant part of /etc/config/network
Make sure correct APN is configured on the modem as shown in https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
Nothing else at the moment.
