Tested on 10g 10.2.0.3 database with default installation(no additional packages were installed to achieve the results)

There are many APIs (developed by 3rd parties) which will allow you to send SMS from a Oracle database on demand. Many times such APIs would become costly, depending upon your requirements.

Here, we are providing a zero cost solution, incase if your SMS gateway provider allows you to send SMS through a web service portal.

You may wrap the entire procedure and call it against a table trigger or through a button click available with user form(s)

SET SERVEROUTPUT ON;
 SET DEFINE OFF;
 DECLARE
 HTTP_REQ    UTL_HTTP.REQ;
 HTTP_RESP   UTL_HTTP.RESP;
 URL_TEXT    VARCHAR2 (32767);
 URL         VARCHAR2 (2000);
 SMS_MSG     VARCHAR2 (160):= 'Congratulations! Your database has been configured propoerly for sending SMS through a 3rd party SMS Gateway';
 BEGIN
 DBMS_OUTPUT.ENABLE (1000000);
 --Based ON your SERVICE provider, THE FOLLOWING LINK FORMAT may differ FROM
 --What we have specified below!
 URL :='http://yourwebsmsdomain.com/alerts/api/web2sms.php?username=demo&password=demo2&to=95xxxxxxx&sender=ODBSMS&message='
 || UTL_URL.Escape (SMS_MSG, TRUE);
 --UTL_URL.Escape manages ESCAPE CHARACTERS LIKE SPACE BETWEEN words IN A message.
 HTTP_REQ := UTL_HTTP.BEGIN_REQUEST (URL);
 UTL_HTTP.SET_HEADER (HTTP_REQ, 'User-Agent', 'Mozilla/4.0');
 HTTP_RESP := UTL_HTTP.GET_RESPONSE (HTTP_REQ);
 -- PROCESS Request
 LOOP
 BEGIN
 URL_TEXT := NULL;
 UTL_HTTP.READ_LINE (HTTP_RESP, URL_TEXT, TRUE);
 DBMS_OUTPUT.PUT_LINE (URL_TEXT);
 EXCEPTION
 WHEN OTHERS
 THEN
 EXIT;
 END;
 END LOOP;
 UTL_HTTP.END_RESPONSE (HTTP_RESP);
 END;

Enjoy another quality solution from us :)
