   try {
            final ITelephony phone =
                ITelephony.Stub.asInterface(ServiceManager.checkService("phone"));

            if(phone!= null && !phone.isSimInsert(simId)){
                status = Status.SimMissing;
            }
        } catch (RemoteException ex) {
            ex.printStackTrace();
        }
