Hi. I've come across at least 4 sites that offer free international calls to certain countries when you dial their access number (an Australian mobile number) from your mobile phone. You are only charged for calling the access number, which is the same cost as dialling any other Australian mobile number. So if you make a 30 minute call to one of the free countries, you will only pay for 30 minutes of national mobile calls charged at the rate set by your mobile provider.
I'm on the 3 $29 cap and if I make a direct call to overseas to the country I call most it will cost me 75 cents per 30 seconds. Very expensive! If I use this service, I will only be charged 35 cents per 30 seconds (3's $29 cap call rate) to make the same call.
I know this isn't the cheapest calling offer, but I think it will be useful for people with a high CAP plan who have plenty of credit or those who are out and about and don't have access to a landline or payphone.
One of the sites are
Please let me know what you think in terms of call quality and if it's worth using the service.
I used this aussiecall, call quality is good. Was thinking of going back to pennytel talk till you drop plan, then you pay 38.8cents untimed to mobile and using this you get more places like india which was otherwise not possible.
