No B/Y have not provided a dial-up number
But it was just a thought.
I do already have a PAYG dial-up account with Supanet (15 years now, my first ever experience of the internet).
So I could always use this because it still works as I have always kept the email address active.
Just was not too sure if B/Y couldn't be worked a little like AOL which has a set of free phone numbers as standard so no matter where it's plugged-in access is available.
Thanks again and if I hear anything different from B/Y when I ask them, I'll let you know. (but don't hold your breath waiting)
