A quick way to make your mobile 'ex-directory'

A new directory service for mobile phones was announced in July.
The data was apparently assembled quite legally but, at 15 million names and numbers (and counting), chances are your details could already be held by them, leaving you potentially open to cold calls, pushy sales people and other unwanted callers.
 
Since then there has been a delay in the launch, but the onus will be on you to request removal from their files and thus go 'ex directory'. Unfortunately, you cannot do this prior to the actual launch, but you need to be ready to do it the minute they go
live, as it takes them some 4 weeks to comply.
 
The most publicised way to do this is via the internet, but there is a quicker, and just as effective a way to go ex directory. All you will  have to do is  simply text the letter 'E' to 118 800 from the mobile phone whose number you want removed from their data base.
