Dropped by Vodafone to change my plan and found they got this going on. Sounds similar to what Optus is offering with international calls being different.
Vodafone's $60 SIM only now has $10 discount and 2GB bonus making it:
$50 per month
8GB Data
Unlimited Calls and TXT in Australia
Unlimited calls to China, India, USA, UK, NZ, Singapore, Thailand, Hong Kong, Sth Korea and Malaysia.
120 minutes of international call outside those 10 countries
I'm doing a month to month so I have some flexibility but was told that if I signed up for 12 months, I get a bonus 1GB making it 9GB.
To see it online, you have to add the $60 sim only plan to the cart and the discount and extra data shows in the cart.
Wasn't it like 300 minutes before
