如何用twilio发送短信到电话号码？

Question

我用jquery创建了twilio sms verificaton的ajax调用。我正确传递所有参数并仅获得肯定响应，但这些消息未传递给该号码。 这是我的ajax代码，

$("#btnSubmit").click(function(){
            // Your Twilio credentials
            var SID = "SID_KEY";
            var Key = "AUTH_TOKEN";

            $.ajax({
                type: 'POST',
                url:'https://api.twilio.com/2010-04-01/Accounts/'+SID+'/Messages',
                data: {
                    "To" : "+xxxxxxxxxx",
                    "From" : "+yyyyyyyyy",
                    "Body" : "Hello World"
                },
                beforeSend: function (xhr) {
                    xhr.setRequestHeader ("Authorization", "Basic " + btoa(SID + ':' + Key));
                },
                success: function(data) {
                    console.log(1);
                    console.log(data);
                },
                error: function(data) {
                    console.log(data);
                }
            });
        });

响应，
