I've decided to change my home hub 1 (white one with a phone) to a new home hub 3.
My first question is :
Do I have to uninstall the old Hub or is it just a question of changing one for the other?
My second question is:
The home hub 3 doesn't have a phone with it, does this mean I will not be able to have a separate broadband phone from now on? If so what happens to my old number?
