Does anyone know if there is a way to prevent unwanted TXTs being sent direct from Vodafone? I am on Simple Prepay. Every so often I get TXTs coming from Vodafone offering some deal or other. Sometimes they are advertising cheap calls or weekend deals, or, like the one I received today, asking for support for the Pike River Miners Relief Fund where $3 is donated if I send a TXT to number 306. These TXTs dont have any phone number attached to them, so I can't associate a different ringtone to them, and there is no option to reply. (Not to be confused with TXTs from Vodafone associated with number 777 which I am happy to receive).  I have looked at my Vodafone prepay account on the Internet, but can't find anywhere to opt out. There are only 2 or 3 TXTs per month, but surely, I should be able to opt out somehow, and only get TXTs from friends and family.
