I have a prepaid deal, I buy a 30 or 50 call card, I make no charged calls but for every 30 card I get 300 minutes free and 500 minutes with a 50 card, when calling other optus prepaid customers

so family & friends all bought the same phone with the same deal, so we all talk to each other for ....nix

and when I have to use up my credits, well I will be alble to calculate on average the costs will be less than the charge rate of 33 second or whatever the crap it is

so thats why I like optus.....
cheers
