Okay let me start by saying if you are looking for sending free SMS messages you are looking at the wrong place. This plugin came to life due to an email I received from a friend over at WebAddiCT(s);, Rafiq Phillips.

The plugin allows users to subscribe their cellphone number via a widget (check my sidebar) and then allows the blog owner to send SMS messages to the subscribed numbers when he/she sees fit.

The plugin is called International SMS Subscription Manager and as the name says this WordPress plugin will allow you to send SMS message to over 819 cellphone networks in 221 countries and territories.

International SMS Subscription Manager for WordPress currently allows users to subscribe and unsubscribe their cellphone numbers in international format (eg. 27730000000). Once the user has subscribed, the blog owner can send SMS messages to the subscribed numbers through the WordPress dashboard.

International SMS Subscription Manager makes use of a widget, making it easy for non tech savvy blog owners to easily get it up and running on their blog.

Future features will include the ability to send SMS updates each time a new post has been made, and also an Ajaxified widget.

You can download your copy of International SMS Subscription Manager here until I get it onto the WordPress Plugin directory, this is the first release so please report bugs as you find them in the comments.
