Maybe the 7 days are just before the transfer happens, mostly impossible to happen
I have just seen that you have the SamKnows Whitebox. I got mine about a week ago just after I switched to PlusNet Fibre but I did order it when I was on O2, how should I contact them to let them know about the change? Or shouldn't I bother? Still not connected as need to sort a spare plug to connect the device. Not looking forward to have 3 devices connected

I also wanted to connect my DGND3300v2 to use the wireless from it instead of the TG582n one, 4 devices would be mad :'(
