Cheap calls to mobiles

Recently there was a posting re above. It gave a link to a website with info on saving money phoning mobiles and also long distance, I think. Can't seem to find the link now. The postee signed off by saying how delighted they were when the last phone bill arrived. Ring any bells?

It may have been deleted as it was spam.

Dring, dring...?
