title: Sending sms through my application coded in vb.net
body: <p>My client requires an sms to be sent to him, whenever an invoice is made on his system by any of the employees.  I have no idea how to configure it.  Do I need to buy any sms-server service?</p>
  
  <p>How to integrate into my application?</p>
  
  <p>Any help will be highly appreciated.
  Thanks</p>
