So it looks like I'm going to keep coming back with questions..!
I had a NowTV combo activated just over a week ago (Tuesday 25th). This included a new BT line.
It's been a week already, and the number still isn't recognised by BT's ADSL checker ( https://www.dslchecker.bt.com/adsl/ ) nor any ISP's checker - though I suppose that's expected if BT's own checker isn't working.
Is this normal? Shouldn't the records appear within a few days? The number is ex-directory, though I'd be surprised if that makes a difference.
