 * Publish SMS: use Amazon Simple Notification Service (Amazon SNS) to send an SMS text message to a phone number.
 * Note: This requires additional AWS configuration prior to running example. 
 * 
 *  NOTE: When you start using Amazon SNS to send SMS messages, your AWS account is in the SMS sandbox and you can only
 *  use verified destination phone numbers. See https://docs.aws.amazon.com/sns/latest/dg/sns-sms-sandbox.html.
 *  NOTE: If destination is in the US, you also have an additional restriction that you have use a dedicated
 *  origination ID (phone number). You can request an origination number using Amazon Pinpoint for a fee.
 *  See https://aws.amazon.com/blogs/compute/provisioning-and-using-10dlc-origination-numbers-with-amazon-sns/ 
 *  for more information. 
 * 
 *  <phone_number_value> input parameter uses E.164 format. 
 *  For example, in United States, this input value should be of the form: +12223334444
