I think I have found full details about this scam. See http://www.commerce.wa.gov.au/ConsumerProtect ... s_Casino_I.html

I suspected it to be a scam and my search led me to this useful site. Thanks. My message (including spaces that were not inserted) was "Last Notice:Your mobile No.has won 3rd prize in our activitieswith cert No.J4192.pls contact us ASAP.or else your award will be cancel.GSCI company:(03) 9010 5705/">(03) 9010 5705" The number of the sender appears on my phone as 4192  (03) 9010 5705. I do not know what the 4192 represents.

i rang them .I told them my name and what town i live in.They wanted my details but i wasn;t game enough and told them to ring back later. I looked up their number online and found this.Thank goodness!
