Archived:Get MCC MNC using CTelephony

From Nokia Developer Wiki
Jump to: navigation, search

CTelephonyReader implementation illustrates how to get MCC and MNC in S60 3rd Edition devices with 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.
