I heard on one of the news programmes today someone reading a newspaper article that mentioned that people could stop those much-regretted drunken mobile phone calls that folk make at 3AM after a night out.
Simply dialling 333 and the number you want to block out means that your provider doesn’t let you ring that number from midnight until 6am, which should cut out a lot of those embarrasing moments I expect.
Strangely though the only references that I could find on the net about this relate to Virgin Mobile Australia [www.virginmobile.com.au] who offer the service.
Lots of people do this according to their survey, so maybe a similar service is to be introduced over here in UK land.

That might have been The Independent, they even had it on their frontpage (as well as a cartoon next to it). Say goodbye to embarrassing drunken phone call misery
i wonder if you can just block off certain people who send you obnoxious text messages at like 3am.
