Hi Karthik,

Can you make sure to start with country code (91) to the given mobile number? also please check does RequestCode returning true/false?

Please Check below link

using Twilio.Rest.Api.V2010.Account;
class Program
{
static void Main(string[] args)
{
// Find your Account Sid and Token at twilio.com/console
const string accountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
const string authToken = "your_auth_token";
TwilioClient.Init(accountSid, authToken);
var message = MessageResource.Create(
