I purchased Axvoice's Pay as You Go plan because it was going to be a temporary arrangement. From their website, I came to know all I had to do was to install an application on my Iphone. I already had wi-fi internet access in my room. I could make and receive local calls to Tennessee within a matter of hours. I am very satisfied with the voice quality. I am planning to switch my home line to Axvoice because this service can be used on touch tone phone set, mobile and also on laptop.
