Keywords (APIs, classes, methods, functions): CTelephony::GetSubscriberId()

CImsiReader example illustrates how to read IMSI (SIM card's identity number, which has nearly nothing to do with the MSISDN that is the phone number used for calling) in 3rd Edition Symbian devices. Note that this code will most likely not work in the emulator, thus you should only use it in real devices.
