If the OP's message is to be accurate, it should read ... "Dial 112 (even) if you have no CREDIT" Clearly, if you have no service then not much is going to happen. But as WYO points out, it is purely fictitious as far as the story goes, - but good advice in a general sense anyway.
No offence intended, but this may need spelling out to some people. I know one person who genuinely thought that scheduling their virus scanner to run conveniently in the middle of the night was a great idea - even though they don't leave the pc on overnight. Go figure
