Overview

The CTelephonyReader class shown below uses the CTelephony API to get MCC and MNC in S60 3rd Edition devices. It does this by extracting them from the IMSI. The IMSI is 15 digits long - the first 3 digits are the MCC, and these are followed by the MNC, either 2 digits (European standard) or 3 digits (North American standard).

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.
