iPhone VoIP is a new way of using your iPhone by making phone calls over the internet with iPhone SIP client apps rather than via traditional mobile operators - thus cutting out the middle man and saving you money.
iPhone SIP client apps enable customers to make free phone calls to other SIPcity users or very cheap phone calls to anyone else in the world from your iPhone using a Bluetooth headset.
iPhone VoIP apps work wherever you have access to the internet via Wi-Fi or over 3G / 4G.
