If you still want to stick with initial design, removed the "location.href='/';" because the page should not redirect back to index and remain on the page.
if (n == 3)
{
return Content("");
}
However, I like the changes that you had made using TempData["Success"]

instead of showing Success or Failure message via javascript i used tempdata in myview as
@if (TempData["Success"] != null)
{

@TempData["Success"]
}
My controller is just setting
if (n == 3)
{
TempData["Success"] = "Message does not Send Successfully due to invalid credentials.";
}

my controller is like below
[HttpPost]
public ActionResult SendSMS(ConfigurationSettings sm)
{

string API_KEY = sm.API_KEY;
string API_SECRET = sm.API_SECRET;
double TO = Convert.ToDouble(sm.To_Number);
string Message = sm.TextMessage;

string sURL;

sURL = "https://www.thetexting.com/rest/sms/json/message/send?api_key=" + API_KEY + "&api_secret=" + API_SECRET + "&to=" + TO + "&text=" + Message;

if (ModelState.IsValid)
{

try
{

using (WebClient client = new WebClient())
{
string s = client.DownloadString(sURL);
var responseObject = Newtonsoft.Json.JsonConvert.DeserializeObject(s);
int n = responseObject.Status;
if (n == 3)
{
return Content("");
}
else
{
return Content("");
}

}
}
catch (Exception ex)
{

ModelState.AddModelError("", "Error in sending Message");
ex.ToString();
}
return View("Index");
}
else
{

ModelState.AddModelError("", "Error in sending Message");
return View("Index");
}
}
}
my view is like below :
@model TheTextingDemo.Models.ConfigurationSettings
TheTexting SMS GateWay Demo
@Html.ValidationSummary(true, "Correct The Errors first.")
@using (Html.BeginForm("SendSMS", "Home", FormMethod.Post))
{

Account Information

Note: all the fields with (*) are required fields.

@Html.LabelFor(model => model.API_KEY, new { @class = "required" })

@Html.TextBoxFor(model => model.API_KEY)
@Html.ValidationMessageFor(model => model.API_KEY)

@Html.LabelFor(model => model.API_SECRET, new { @class = "required" })

@Html.TextBoxFor(model => model.API_SECRET)
@Html.ValidationMessageFor(model => model.API_SECRET)

@Html.LabelFor(a => a.To_Number, new { @class = "required" })

@Html.TextBoxFor(a => a.To_Number)
@Html.ValidationMessageFor(a => a.To_Number)

@Html.LabelFor(a => a.TextMessage, new { @class = "required" })

@Html.TextAreaFor(a => a.TextMessage, new { @Value = "test" })
@Html.ValidationMessageFor(a => a.TextMessage)

Note:

Number must be international format like for USA : 13306807200 (where prefix 1 is USA country dialing code)

Hi Mark Tabor,

You can pass the text box values using ajax method in view

Kindly find the below code,
//controller

Public ActionResult ActionName(ModelName modelObject)
{
// Write your code here to save the data
return Json(true,JsonRequestBehavior.AllowGet);
}

//Model

public class SampleModel
{
public string Textbox1{get;set;}
public string Textbox2{get;set;}
}
