We have 2 BT phone lines in our house.
I currently have BT Broadband on our PC on phone line A. I've just purchased O2 Broadband and want to put this on our PC using phone line B. I'm going to cancel BT Broadband and phone line A.
I presume that a MAC code is required for switching broadband providers on the same phone line. I'm not doing this so I guess I don't need a MAC code. Is this correct?
