Here is a example off the plugin please test.
== Description ==
I created this simple plugin to use clicktells api text system it basically displays a form using the shortcode [ sms ] within any post or page so people can just send you a text instantly to your phone or a number off choice.
This is in its very basic stages at the moment but i am hoping to really extend this plugin in the coming months.
= Features =
Sends a SMS text to any phone as long as you prefix 44 instead off 0 i.e 447702220558

Upload the ISD Clicktell Text Plugin to your blog, Activate it, and then use the shortcode [ sms ] anywhere within your template, if you have any ideas for this plugin please contact me.
