geek4me: Ok, thanks. I guess I had put more trust in the address checker then I should. Perhaps a note should be added to say that the results are only a general reference to whats available in the area and recommend that users ring the Help Desk to make sure. Asking for a specific street number like 8B is a little misleading if it is indeed only a general reference to whats available in the area.
The popup box asking for your address already says this
"Enter your address details below and we'll tell you what Vodafone services may be available in that area"
and
"Please use this as a guide as a full service check is only possible when we process an application. In some cases, as a result of further checks, some services may not be available"
