如何检测某人的SIM卡是否有效

Question

我每天有40到50个电话号码。目前我们手动呼叫每个人以检测每个人的状态，如电话号码是否有效（如果是呼叫振铃）。我想以编程方式执行此操作。有可能，以编程方式呼叫每个号码，如果电话铃声正在进行，那么设置它的状态是否有效，否则无效？

是的，这是可能的，但最好使用短信发送报告来检查android你可以创建一个程序，如果它显示发送报告比自动添加到活动否则不活动

BroadcastReceiver sendBroadcastReceiver = new sentReceiver();
    BroadcastReceiver deliveryBroadcastReciever = new deliverReceiver();;

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();

        try {
            unregisterReceiver(sendBroadcastReceiver);
            unregisterReceiver(deliveryBroadcastReciever);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    try {
        unregisterReceiver(sendBroadcastReceiver);
        unregisterReceiver(deliveryBroadcastReciever);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

    send_sms.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if (textView.getText().toString().equals("")
                        | textView.getText().toString().equals(null)) {
                    Toast.makeText(SendSMS.this, enter_ph_no, Toast.LENGTH_LONG)
                            .show();
                } else {


                        sendSMS(textView.getText().toString(), "sms_content");
                        finish();


                }

            }

        PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(

                new Intent(DELIVERED), 0);

        registerReceiver(sendBroadcastReceiver, new IntentFilter(SENT));

        registerReceiver(deliveryBroadcastReciever, new IntentFilter(DELIVERED));
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);


    }
