Thanks for the suggestion. I did a bit of digging and it looks like my firewall supports any BSD compatible cellular modem, so might try that.

I’m happy with the service 3 provide, my question is for a 3rd party router that supports 4/5g

The only other option I have is Openreach/BT who will only give me 4mb down 1mb up. At least I get 50mb with three.

I’m happy with 3, it’s just their router is shit.
