title: how to subscribe a list of phone numbers to a aws-sns topic
body: <p>I need to send 200 sms messages, and looking in the amazon documentation I found how to do this by subscribing to a topic but only one by one.</p>
  
  <pre><code>public static void main(String[] args) {
    AmazonSNSClient snsClient = new AmazonSNSClient();
    String phoneNumber = "+1XXX5550100";
    String topicArn = createSNSTopic(snsClient);
    subscribeToTopic(snsClient, topicArn, "sms", phoneNumber);
  }
  
  
  public static void subscribeToTopic(AmazonSNSClient snsClient, String topicArn, 
          String protocol, String endpoint) { 
          SubscribeRequest subscribe = new SubscribeRequest(topicArn, protocol,
                                                            endpoint);
          SubscribeResult subscribeResult = snsClient.subscribe(subscribe);
  }
  </code></pre>
  
  <p>Is there any way I send a list of phone numbers to the endpoint, or I subscribe a list of SubscribeRequest?</p>
