I am listing some of them for you and you can download the from iphone apps store and hope this will help you. You can get Skype software, Skype has become so synonymous with VoIP and in this not only calling you can even use free video calling as well and it is among one of the best. It’s high-quality, simple to use, and very reasonably priced. It can make calls over both WiFi and 3G. One of the companies that are most obviously trying to compete with Skype is Fring. But the different between this and skype is that this will not provide calling plans like Skype, Fring charges on a per-minute basic.
