Well I guess it depends on your opinion - unlimted "calls" after 7pm (if anything like Canada) is pretty useless to me, unless you only call someone close by in your "local" calling area.

With the Get Connected plans (or the Business Mobile Select plans - $55 unlimited calling/incoming/texting (no "call connection" charge) you can call any landline in the country, so if you make long calls and don't just call people in your "local" area then this is much better value then the plans I've seen in Canada and in some ways better for me than the plans in the US.

I have to admit that the Mobile to Mobile calls in the US are pretty good, unless it's only limited to a certain geographical area?

No you got it wrong, I was worried about People calling me in Canada because I was paying 0.35c/minute when they called! Why would I care how much they paid? Here since all incoming (even long distance) is free I have no qualms in talking as long as needed. On the other hand in Canada my meagre $20 recharge barely lasted a week even though I had unlimited evenings starting at 6pm for only $1/day. The reason is because the incoming calls are charged that $20 credit (+$3 taxes) is not the same as an equivalent $30 credit in Australia. Overall you get more for your money in Oz (well subjectively for me). But yes it does suck in the sense that you are either stuck with certain networks, or high per minute rates when calling from landline - to mobile.

I suspect that there are merits to each system, and no one system is clearly superior to the other. Both have their advantages, and I doubt that Australia will ever adopt the US system, or vice-versa. There is hope in the sense that the ACCC is forcing Telstra to drive down their wholesale price so that calls will be cheaper for everyone. Take a look at some of the Asian countries like HK where the system is similar to Oz (free incoming calls) but yet the cost per minute to call a mobile there is not very high (as low as $0.04cents/min with some voip providers) and the reason is because there is true competition there. So provided that there is competition the Australia/Europe system can be as cheap as the US one.
