title: [RestException [Error]: The 'To' number 9977428080 is not a valid phone number
body: <p>I am trying to send sms to number using Twilio API's, but I am getting  error like <code>[RestException [Error]: The 'To' number 9977428080 is not a valid phone number.] {
    status: 400,
    message: "The 'To' number 9977428080 is not a valid phone number.",
    code: 21211,
    moreInfo: 'https://www.twilio.com/docs/errors/21211',
    detail: undefined
  }</code> </p>
  
  <p>before this I was getting <code>the from number is not valid</code> then I switched my API's credentials testing to  Live credentials, the I got this another issue.
  These are the code below</p>
  
  <pre><code>const client = require('twilio')(config.SId, config.AccesToekn);
  // SEND OTP TO USER ACCOUNT
  router.post('/sendsms',(req, res, next)=&gt;{
  client.messages.create({
       from:'+15204770942',
       to:"9977428080",
       body:'Please user this OPT to verify your number 74536',
   }, function(error, data){
       if(error){
     console.log(error,'error')
      console.log(data,"data")
       }
   })
  })
  </code></pre>
  
  <p>and My credential are  correct.
  What might be cause of  occurring this issue, any your help would be highly appreciated</p>
  
  <p>Thanks in Advance </p>
