This is the WhitePages online SMS sender, allowing you to send white pages listings to your mobile for free.They are not automated, and are manually sent - so someone must have chosen a listing, and entered your number, for you to have received these messages.

Yeah sure tough guy ...

Got FIVE messages from the number tonight, with the address and number of the Crazy Horse, Adelaide Psychological Services, The B***h is Back, XXX Waxing and something about fortune cookies respectively.
Incredibly annoying but seems to have stopped.

I say find these a**holes ringing very late at night and give them a 'special' talking text message that they will remember for a long long time.
