Programmatically retrieve IMEI number for dual SIM in android

Question

For single SIM following code works:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
String imei= tm.getDeviceId();

Answer 1

You can IMEI in Android O or above.

Set<String> deviceIdList = new HashSet<>();
TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
int phoneCount = telephonyManager.getPhoneCount();
for (int i = 0; i < phoneCount; i++) {
   deviceIdList.add(telephonyManager.getImei(i));
}

Answer 2

Steps: 1 > You must have READ_PHONE_STATE Permission enabled

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

2 > For Android SDK v23<= get SIM 1 & SIM 2 IMEI by this:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    Log.e("IMEI---1:", tm.getDeviceId(0) );
    Log.e("IMEI---2:", tm.getDeviceId(1) );

Answer 3

Try following code to get IMEI Number for an Android Device:

telephonyManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);

    btn_imei.setOnClickListener(new View.OnClickListener() {
        @RequiresApi(api = Build.VERSION_CODES.O)
        @Override
        public void onClick(View v) {
            if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) 
            {
                ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE);
                return;
            }

            StringBuilder stringBuilder = new StringBuilder();
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                for (int i = 0; i < telephonyManager.getPhoneCount(); i++) {
                    stringBuilder.append(telephonyManager.getImei(i));
                    stringBuilder.append("\n");
                }
            }
            txt_imei.setText(stringBuilder.toString());
        }
    });

TelephonyManager telephony = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
    try {

        Class<?> telephonyClass = Class.forName(telephony.getClass().getName());
        Class<?>[] parameter = new Class[1];
        parameter[0] = int.class;
        Method getFirstMethod = telephonyClass.getMethod("getDeviceId", parameter);
        Log.d("SimData", getFirstMethod.toString());
        Object[] obParameter = new Object[1];
        obParameter[0] = 0;
        TelephonyManager manager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
        String first = (String) getFirstMethod.invoke(telephony, obParameter);
        Log.d("SimData", "first :" + first);
        obParameter[0] = 1;
        String second = (String) getFirstMethod.invoke(telephony, obParameter);
        Log.d("SimData", "Second :" + second);

    } catch (Exception e) {
        e.printStackTrace();
    }

try using this,this should help getting both device id on android lollipop

Answer 5

AFAIK it is not possible. The java reflection, you used could work for some devices but not all. However there might be some manufacturer specific API's that allows for this.

Quoting Commonsware,

Android does not support multiple SIMs, at least from the SDK. Device manufacturers who have created multi-SIM devices are doing so on their own. You are welcome to contact your device manufacturer and see if they have an SDK add-on or something that allows you to access the second SIM.

Answer 6

We can check whether phone single or dual sim by using Android API and IMEI for each sim Card

TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
Log.i("OmSai ", "Single or Dula Sim "+manager.getPhoneCount());
Log.i("OmSai ", "Defualt device ID "+manager.getDeviceId());
Log.i("OmSai ", "Single 1 "+manager.getDeviceId(0));
Log.i("OmSai ", "Single 2 "+manager.getDeviceId(1));
