TelephonyManager getSubscriberId() and getSimSerialNumber() return null in android Q!

I'm coding in java with android studio IDE!

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.getSimSerialNumber(); //it is null

  • Have you used permission in manifest> – Abhinav Gupta Jul 24 '19 at 10:04
  • Please read the Reference: https://developer.android.com/reference/android/telephony/TelephonyManager.html#getSimSerialNumber() – emandt Jul 24 '19 at 10:05
  • @Abhinav__Gupta I have added READ_PHONE_STATE permission and it is granted by the user. – Mahdi Bagheri Jul 24 '19 at 10:15

  • @emandt I have read that but unfortunately I don't understand how to implement it. – Mahdi Bagheri Jul 24 '19 at 10:27
  • @MasoudKeshavarz Thx, This returns null only in android Q that's the problem! – Mahdi Bagheri Jul 24 '19 at 10:30

    @MasoudKeshavarz it's all written in some guide/Reference like this: https://developer.android.com/preview/privacy/data-identifiers The Permission you need is PRIVILEGED and cannot be used by normal Apps: "Starting in Android Q, apps must have the READ_PRIVILEGED_PHONE_STATE privileged permission in order to access the device's non-resettable identifiers, which include both IMEI and serial number. - Caution: Third-party apps installed from the Google Play Store cannot declare privileged permissions." – emandt Jul 24 '19 at 10:40
  • @emandt So what's the solution? – Mahdi Bagheri Jul 24 '19 at 12:45
  • @MahdiBagheri (1) you can use Root Permissions to bypass this limit or (2) you can sign the final APK using the System/OS Certificate (but that specific APK could be executed only on that specific OS) – emandt Jul 24 '19 at 13:59

If your apk's targetsdk <30, you can get ICCID by the following method without any permission even in android 11.

    Uri uri = Uri.parse("content://telephony/siminfo");
Cursor cursor = null;
ContentResolver contentResolver = getApplicationContext().getContentResolver();
cursor = contentResolver.query(uri,
        new String[]{"_id", "sim_id", "imsi","icc_id","number","display_name"}, "0=0",
        new String[]{}, null);
if (null != cursor) {
    while (cursor.moveToNext()) {
        String icc_id = cursor.getString(cursor.getColumnIndex("icc_id"));
        String imsi_id = cursor.getString(cursor.getColumnIndex("imsi"));
        String phone_num = cursor.getString(cursor.getColumnIndex("number"));
        String display_name = cursor.getString(cursor.getColumnIndex("display_name"));
        int sim_id = cursor.getInt(cursor.getColumnIndex("sim_id"));
        int _id = cursor.getInt(cursor.getColumnIndex("_id"));
        Log.d("Q_M", "icc_id-->" + icc_id);
        Log.d("Q_M", "imsi_id-->" + imsi_id);
        Log.d("Q_M", "phone_num-->" + phone_num);
        Log.d("Q_M", "sim_id-->" + sim_id);
        Log.d("Q_M", "display_name-->" + display_name);
    }
}

public String getSimSerialNumber () Returns the serial number of the SIM, if applicable. Return null if it is unavailable.

Requires Permission: READ_PRIVILEGED_PHONE_STATE, for the calling app to be the device or profile owner and have the READ_PHONE_STATE permission.

See the following link: getSerialNumber()
