Get MSISDN from the SIM using Android

Question

I\'m trying to retrieve the MSISDN from the SIM using Android, I have tried getLine1Number() but this only returns the MSISDN stored in My Phone Information

Answer 1

The MSISDN (aka the mobile phone number) isn't a SIM data, so you can't retrieve it. The SIM card has an IMSI (International Mobile Subsriber Identity) that is sent to the HLR (Home Location Register) in charge of doing the mapping MSISDN/IMSI. Mobile phone operators could store the MSISDN on the SIM card if they wanted to, but since it is not required in the GSM protocol it isn't.

Sorry!

EDIT:

To get IMSI number,

 TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
 String imsi = mTelephonyMgr.getSubscriberId();

but a few handsets only return 6 digits instead of 15. So, you can use,

According to this post: http://www.anddev.org/tinytut_-_getting_the_imsi_-_imei_sim-device_unique_ids-t446.html

String imei = android.os.SystemProperties.get(android.telephony.TelephonyProperties.PROPERTY_IMSI);
