Maybe you’ve not heard about this but early next week all UK mobiles will be on a directory which will mean that anyone will be able to access the numbers (118800). It is easy to unsubscribe but it must be done before the beginning of next week to make sure that you are ex directory. The way the system works is 118800 send you a text from someone who is trying to contact you with their details. It is then up to you whether to contact them or not. I have unsubscribed and you may want to suggest it to all your friends and family who have UK mobiles or they could be swamped by unsolicited messages. Removal is recommended by the BBC - see link below.
The Directory of Mobile Phone numbers goes live next week.
To remove your number use the link below (you need your mobile phone with you to do this, they text you a code)
Click on HOMEPAGE at the bottom of the screen then EXDIRECTORY at the top of the following screen then follow the on screen instructions.
You can remove your number from this list, and tell all your friends - especially those with children who have mobile phones. I personally believe my mobile number is private and I should be able to chose who I give it to - none of us agreed to this when we signed our mobile phone contracts.
