Heya trying to setup a connection to Skinny with an old 3G usb modem ( I only need 3g for this project )

I've followed some good guides on this, modem is recognised just can't connect

I'm using a sim card that I got out of one of their provided 4g modems.  The apn below is from here

Maybe its because I'm trying to use a 3g connection here, instead of 4g 🤔

Anyway detials;

/etc/NetworkManager/system-connections/skinny.nmconnection
```

[connection]
id=skinny
uuid=a33fab81-7e03-447c-8a9f-583b390b8985
type=gsm
permissions=

[gsm]
apn=skinnybroadband
sim-operator-id=53005

[ipv4]
dns-search=
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

[proxy]
```

Here is Syslog while executing
`nmcli c up skinny`
