Looking at this page on Vodafones web site,
It states that if you send a txt to 262, and you need a sim2, they will send you "a $20 credit note to show at your nearest Vodafone store, so you can grab a new sim2 and $10 of airtime for just $9.95"
Well, I sent the message as specified, and the text I received stated
"We're sorry, you need to upgrade your SIMcard to use Hotlink.SIM upgrade packs are available at any Vodafone outlet."
No mention of the credit note...
