If you wanted just to call one person, to a fixed location. there is a better option than go trought carriers.
Get a couple of Aplio ‘s from E-bay. Send one to your daughter and you could call each other and talk for alomst free for as many hours as you like.
The only cost is the internet access on each end , like few dollars a month on the U.S and whatever they charge down under.
There are two Aplio versions. The dial-up (Aplio phone) and the Aplio Pro (for broadband,like cable and ADSl).
I used them a lot before I got Quintum Tenors in both ends, becaming my own carrier.
