title: Amazon SNS - Sending SMS, delivery status
body: <p>I am trying to send messages using Amazon SNS but it's showing atypical behavior. It sends messages to some of the numbers while may or may not to others. </p>
  
  <pre><code>import boto3
  client = boto3.client('sns', .....)
  client.publish(PhoneNumber, Message)
  </code></pre>
  
  <p>I am using the publish API to directly send SMS for OTPs without using Topics. Is there a way I can get the delivery status for them? Would region/DND affect the delivery. This is for Indian numbers. I am using Transactional messages for the same. </p>
