Actualización 23 de marzo de 2015:
La API oficial de múltiples SIM ya está disponible desde Android 5.1 en adelante
Otra posible opción:
Puede utilizar la reflexión de Java para obtener ambos números IMEI.
Con estos números IMEI puede comprobar si el teléfono es DUAL SIM o no.
Prueba la siguiente actividad:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyInfo telephonyInfo = TelephonyInfo.getInstance(this);
String imeiSIM1 = telephonyInfo.getImsiSIM1();
String imeiSIM2 = telephonyInfo.getImsiSIM2();
boolean isSIM1Ready = telephonyInfo.isSIM1Ready();
boolean isSIM2Ready = telephonyInfo.isSIM2Ready();
boolean isDualSIM = telephonyInfo.isDualSIM();
TextView tv = (TextView) findViewById(R.id.tv);
tv.setText(" IME1 : " + imeiSIM1 + "\n" +
" IME2 : " + imeiSIM2 + "\n" +
" IS DUAL SIM : " + isDualSIM + "\n" +
" IS SIM1 READY : " + isSIM1Ready + "\n" +
" IS SIM2 READY : " + isSIM2Ready + "\n");
}
}
Y aqui esta TelephonyInfo.java:
import java.lang.reflect.Method;
import android.content.Context;
import android.telephony.TelephonyManager;
public final class TelephonyInfo {
private static TelephonyInfo telephonyInfo;

}*/

}
/*public static void setImsiSIM2(String imeiSIM2) {

}

Editar:
Obtener acceso a métodos como "getDeviceIdGemini" para obtener detalles de otras ranuras SIM permite predecir que el método existe.
Si el nombre de ese método no coincide con uno proporcionado por el fabricante del dispositivo, no funcionará. Debe encontrar el nombre del método correspondiente para esos dispositivos.
La búsqueda de nombres de métodos para otros fabricantes se puede realizar mediante la reflexión de Java de la siguiente manera:
public static void printTelephonyManagerMethodNamesForThisDevice(Context context) {
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> telephonyClass;
try {
telephonyClass = Class.forName(telephony.getClass().getName());
Method[] methods = telephonyClass.getMethods();
for (int idx = 0; idx < methods.length; idx++) {
System.out.println("\n" + methods[idx] + " declared by " + methods[idx].getDeclaringClass());
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
EDITAR:
Como señaló Seetha en su comentario:
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceIdDs", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceIdDs", 1);
Está funcionando para ella. Tuvo éxito al obtener dos números IMEI tanto para la SIM en el dispositivo Samsung Duos.
Añadir <uses-permission android:name="android.permission.READ_PHONE_STATE" />
EDITAR 2:
El método utilizado para recuperar datos es para Lenovo A319 y otros teléfonos de ese fabricante (Credit Maher Abuthraa ):
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 1);
