Hello I am using Mysmsmantra as an gateway provider and my site is on latest drupal 7.25.

There is Mysmsmantra sms gateway module for drupal 6.

Please help me to intigrate Mysmsmantra with drupal 7 smsframework module.

they have provided me this code

<?php
$url = "http://bulksms.mysmsmantra.com:8080/WebSMS/SMSAPI.jsp?username=username&password
=password&sendername=sender id&mobileno=919999999999&message=Hello";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
