How do I get the phone number in Windows Mobile?

Some time ago, many friends asked, how to get the phone number. There is an IMSI (International Mobile Subscriber Identity) Record on the SIM card, but this is not a phone number. It is estimated that in the server side, the phone number corresponds to the IMSI, and the specific Record case can refer to the SIM GSM File System specification. Note: This article comes from Windows Mobile Team Blog. The code part has been tested (in Shanghai Mobile Network, Yitong Card), failed to get the phone number, may be the service provider without providing the service. Interested friends can refer to it.
