Can't able to send SMS using Twilio Trail Account using C# - sms

Question

I'm just trying to use Twilio to send transaction SMS. I have tried exactly the same code which is provided in the Twilio Documentation
static void Main(string[] args)
{
try
{
// Find your Account Sid and Token at twilio.com/console
const string accountSid = "AC5270abb139629daeb8f3c205ec632155";
const string authToken = "XXXXXXXXXXXXXX";
TwilioClient.Init(accountSid, authToken);
var message = MessageResource.Create(
from: new Twilio.Types.PhoneNumber("[phone]"),
body: "Body",
to: new Twilio.Types.PhoneNumber("MyNumber")
);
Console.WriteLine(message.Sid);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
in this authToken copy from Twilio console and the TO number is my number which is used to register on Twilio. I also have verified the number in Verified Caller IDs segment in Twilio Console.
From Number initially, I was using the number which is generated by in Twilio Console the Number Belongs to the US but it won't work. After Reading this
Article I used the Exact code provided by Twilio just make the Changes as authToken and TO Number. But still, it won't work.
I have No idea why it Does not Work. is that you Can't Send the message from one country to another country?

Answer 1

As I want to Verify Mobile number by sending code from SMS. so achieve this I'm using
Twilio Verify API here where the Code is generated by Twilio and verified by himself.
this Solve my problem.
TO Send SMS :-
var client = new HttpClient();
var requestContent = new FormUrlEncodedContent(new[] {
new KeyValuePair<string,string>("via", "sms"),
new KeyValuePair<string,string>("phone_number", "Moblienumber"),
new KeyValuePair<string,string>("country_code", "CountryCode"),
});
// https://api.authy.com/protected/$AUTHY_API_FORMAT/phones/verification/start?via=$VIA&country_code=$USER_COUNTRY&phone_number=$USER_PHONE
HttpResponseMessage response = await client.PostAsync(
"https://api.authy.com/protected/json/phones/verification/start?api_key=" + "Your Key",
requestContent);
// Get the response content.
HttpContent responseContent = response.Content;
// Get the stream of the content.
using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
// Write the output.
Console.WriteLine(await reader.ReadToEndAsync());
}
return Ok();
To Verify :-
// Create client
var client = new HttpClient();
// Add authentication header
client.DefaultRequestHeaders.Add("X-Authy-API-Key", "Your Key");
// https://api.authy.com/protected/$AUTHY_API_FORMAT/phones/verification/check?phone_number=$USER_PHONE&country_code=$USER_COUNTRY&verification_code=$VERIFY_CODE
HttpResponseMessage response = await client.GetAsync(
"https://api.authy.com/protected/json/phones/verification/check?phone_number=phone_number&country_code=country_code&verification_code=CodeReceivedbySMS ");
// Get the response content.
HttpContent responseContent = response.Content;
// Get the stream of the content.
using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
// Write the output.
Console.WriteLine(await reader.ReadToEndAsync());
}
return Ok();
