Programmatically get own phone number in Symbian

Question

How to get the phone number of the device in Symbian?

Answer 1

According to the GSM specs, only the IMSI is required to be available on the SIM card.

The actual phone number MSISDN is stored on the HLR database in the operator's network and does not need to be available on the SIM card or transmitted to the phone.

So no matter what technology you are using (Symbina, Java ...) you can never count on being able to consistently get your own phone number from the device or SIM. You might be lucky if the operator stores it on the SIM or if the phone provides the user with a possibility to enter it manually, but it does not have to be this way.
