Remember in The Stolen Earth when Torchwood, Sarah Jane, Harriot Jones, Rose and Martha were all trying to call the Doctor? And his personal phone number - 07700 900461 - was shown many times on the screen? Well, it wasn't just the Doctor's companions trying to call him - more than 2,500 fans tried the line, but all they were given was a dead dial tone. Here's what some of the fans had to say:
"Grrr - I phoned the Doctor's phone number but there was just an annoying network message."
"What's the point in showing a phone number if you're not gonna use it?!"
"They showed that number so many times, as if they were asking for it to be called."
