Overview
CTelephonyReader implementation illustrates how to get MCC and MNC in S60 3rd Edition devices with CTelephony API. Basically IMSI is 15 digits long number. The first 3 digits of IMSI are the MCC, and is followed by the MNC, either 2 digits (European standard) or 3 digits (North American standard). So retriving MCC and MNC from IMSI is not always safe, thus implemented this method to get MCC MNC from CTelephony::GetCurrentNetworkInfo() API of symbian.
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.
