Description:

I have a 4G modem reported by lsusb as following:
Bus 001 Device 003: ID 1199:9079 Sierra Wireless, Inc.

I'm using the latest versions of:
libmbim 1.14.2-1
modemmanager 1.6.10-1
networkmanager 1.10.0-1

Everytime I try to connect to a GSM network from network manager, it fails with the error: "Error: Connection activation failed: The base network connection was interrupted". As well modem manager fails:
```
