The SmtpAppender has parameters named "to" and "from":

 <to value="to@domain.com" />
 <from value="from@domain.com" />

This is what those parameters look like in code on the SmtpAppender
class:

 public string To 
 {
  get { return m_to; }
  set { m_to = value; }
 }
 
 public string From 
 {
  get { return m_from; }
  set { m_from = value; }
 }

Your SMSAppender should have a public property named
SMS_Alert_MobileNumbers:

 public string SMS_Alert_MobileNumbers
 {
  get { return smsAlertMobileNumbers; }
  set { smsAlertMobileNumbers = value; }
 } 

Here's what your config file will look like:

 <?xml version="1.0" encoding="utf-8" ?>
 <log4net>
  <appender name="SMSAppender" 
   type="CustomLog4NetAppenders.SMSAppender, CustomLog4NetAppenders">
   <SMS_Alert_MobileNumbers value="5628241460" />
  </appender>
  <root>
   <appender-ref ref="SMSAppender" />
  </root>
 </log4net>

The error message you're seeing is log4net telling you its unable to
find a property named "SMS_Alert_MobileNumbers" on one of log4net's
internal objects.
