Overview

CTelephonyReader implementation illustrates how to get Operator Name in S60 3rd Edition devices using CTelephony API.

The implementation is pretty simple, and when using this one only thing to do in calling class is to implement the callback interface and then to construct an instance of the CTelephonyReader.
