How to save money on phone calls?

Hey guys. I'm currently living in Florida. I'm going to Melbourne next week. Can anybody give any advices about what roaming SIM card to use there? Should I buy any special International card to call from Melbourne to Florida?

If you have an iphone or android phone and you are planning on calling another iphone or android phone you could install an app called viber - I've found it pretty handy when overseas.

Dude we just bought prepaid phone cards while in Hawaii. You can get them all over the world and they are super cheap and you can use them from any public or hotel phone. So cheap we called home a few times and still didn't use up all the credit on them and they only cost about $10 each.

I call europe and Brazil a lot and I baught a few prepaid phone card, cost is less than $0.01 per minute!

have real privacy concerns about Viber. Do you know you agreed to have a copy of your address book stored on their server for ever (it's already happened when you installed the app). it's currently free but if they want to make money out of it then they can do what ever they like with your contacts.
Viber is free, so they must be chewing through venture capital at the moment to support the service. When this runs out then they will have to generate income or shut down. Their privacy policy is very sketchy chats.viber.com/priva cypolicy.html. The company is also based in Cyprus. It is not an EU member so does not have to comply with EU privacy laws.
