const sns = new AWS.SNS();

//exports.sendSMS =
function sendSMS(to_number, message, cb) {

  sns.publish({
      Message: message,
      Subject: 'Admin',
      PhoneNumber:to_number
  }, cb);

}

// Example
sendSMS("+525....", "Sms text message", (err, result)=>{
  console.log("RESULTS: ",err,result)
})

Thanks for the above information.

In the recent version, subject not working as expected.
Just to mentioned here about update of publish request payload.

{
      PhoneNumber: mobile,
      Message: message,
      MessageAttributes: {
        'AWS.SNS.SMS.SenderID' : {
          DataType : 'String',
          StringValue: 'Subject here'
        }
      }
};
