Got an email from 2degrees. Basically I can give a friends name and email to 2degrees, and the friend will get a free SIM and $10 credit if the SIM is activated and topped up before 14 July 2010. I will also get a $10 credit. This is limited to 10 friends.
So if anyone would like a 2degrees SIM and $10 credit then PM me your name and email address.
