In reply to a post by uno:

Quite possibly... but have just tried with a different number and it returned.

Who knows why it is problematic. A good tool when it works though.

Failed miserably earlier on. Working for me now both with and without the leading 0.

Curious indeed.

I'm currently with Virgin (last 2 years), with Sky before that (at least 4-5 years) yet it still lists my number as being held by BT who I haven't been with for YEARS.

Could this explain why when I enquired about moving back to Sky a few weeks ago it flagged an issue with transferring the number?
