Hi,

This is due to you are missing [Web Method] attribute on your service method, this will cause your method will not be exposed.

Try to modify your CallMethod as following:

 [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/Send", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[Web Method]
        public object[] CallMethod(string method, object[] parameters)

        {

            try

            {

                object[] results = this.Invoke(method, parameters);

                return results;

            }

            catch (Exception ex)

            {

                throw ex;

            }

        }

Thanks

Here you can see my method. I have the [WebMethod]. Anyway I'm going to try with your callling.

namespace WebserviceLayer
{
    /// <summary>
    /// Summary description for SMS
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class SMS : System.Web.Services.WebService
    {

        [WebMethod]
        public bool Send(string receiver, string message, bool isUrgent, string businessArea, string userName )
        {
            ISmsService smsService = new SmsService();
            return smsService.SendSms(receiver, message, isUrgent, businessArea, userName, DateTime.Now);
        }
     }
}
