Hi Peter
The mini router is a GL-iNet GL-MT300N-V2(Mango) - I got mine from amazon.fr
I had to configure it - I use ExpressVPN currently to get the Geo restricted services (it was a manual config as ExpressVPN do not have an auto config for this particular router)
We use the phone via the live box, no extra line for us. The livebox is a livebox 4.
