iZone Telecom provides Defne’s Seamless Roamer Callback Service which enables roamers to seamlessly make a call with low rates when they are abroad. The outbound roaming calling party wants to make a normal call to destination without any prefix or service number.


SRC gets the call, cuts it and performs a call back to both the outbound roamer and called party. It starts charging only when both parties have been connected.
