The Directory of Mobile Phone numbers goes live next week. Mobile phone numbers, including those belonging to children, will be open to cold calling and available to all. All mobile phone numbers will be included, without prior permission from the owner — unless you choose to opt out of the service.

To remove your number, go here www.118800.co.uk .

(click on ex-directory at the top of the page you are taken to the remove page. The security code will be sent to your mobile almost immediately).

Enter the code sent to your mobile and you will then be ex-directory.
