A new Directory Enquiries Service will be launched later this month. It hold millions of UK mobile telephone numbers, names and addresses. There are 42,000,000 mobiles (cell phones) in the UK and a good proportion will be available from this new Directory Enquiry Service. Have you opted out yet? You can become ex-directory by contacting the company direct. It takes 4 weeks for them to remove your details (if they have them).

Details are found at the following link. Another option is to change your number with your provider or buy a new mobile phone (with a new number) and opt out from the start.
