A small Code Which Sends SMS from your ASP.Net Application

For it to work the Application you will need -
1) Account in
2) Fill the FromNumber, FromPassword before starting to send sms

private void SendSMS(string ToNumber, string Message)
SendSms.SendSMS objSms = null;
objSms = new SendSms.SendSMS();
objSms.AllowAutoRedirect = false;
if (!(objSms.sendSMSToMany(FromNumber, FromPassword, txtTo.Text, txtMessage.Text).Contains("done")))
lblError.Text = "some error in port. Please try after some time";
lblError.Visible = true;
lblError.Text = "Message sent successfully";
lblError.Visible = true;
catch (Exception)
if (objSms != null) objSms = null;

In the above code 'SendSms.SendSMS' is a web service where you need to add web reference to your project

To Add that to your project solution explorer right click->Add Web Reference
type the url or copy paste the below url

And in Right Side Corner you find the Web Reference Name there give 'SendSms' or what ever you want

Hope that will help some one

it according to the account you have created in

if you register account from any other country you have to give your account number and account password

and in even you can login with email but in my code you have to login with phone number that you have registered!!!!!
