Integrating an SMS gateway into the SMS Framework Module

I have been using Drupal for about a month now and boy o boy I wonder how I never heard about it. I have built a site for ahome delivery service in Nigeria www.granmakitchenng.com

I am trying to integrate the order form to send sms messages. I successfuly created a rule to send sms via an email to sms service (www.etextmail.com. This works fine to an extent though it keeps truncating my sms text. it does not do this when i send the same content directly via email. so it seems my drupal form is somehow doing it even though i don't see the logic since my email looks complete when i check it out.

I got the API from the gateway service but I would need to integrate it to Drupal. Rather than do a shuddy job, I thought it would be nice to extend the SMS Framework module.

I need pointers on how to approach this. I already went through the onthisdate module tutorial, so i am getting there somehow. It looks doable and I would love to work on this with help from the community. Drupal sure rocks. Now I know why it has been tough building a great site in a short time. We try alone

Can anyone assist. There are 3 files.

SendSms.html - HTML file for sending SMS via the web using PHP
SendSmsHttp.php - PHP source code for sending SMS
PostRequest.php - PHP source code for posting HTTP requests to the API server
