SMS API

Hi everyone

I am new to .NET, I want to build a website to send SMS, But do not know how to go about it at all. I have the SMS API, details below

Using an SMS API: www.jvmorris.net/api/jv_api.php?usr=***&pass=**&sid=me&rec=234****&msg=from JVmorris API&typ=0
usr = the registered username on jvmorris.net
pass = appropriate password on jvmorris.net
sid = senderid (what to be displayed to the recipient)
rec = recipient's mobile number (must be in the format - 2348000000000)
msg = message to be sent
typ = type of message the default is 0

Pls help...
