Kwickee

From Kwickee's website:

Kwickee™, The Mobile Information Exchange™, is a platform that allows anyone or any company to share information, knowledge and experiences. Using mobile phones we deliver Kwickee™ directly to the end user whenever and wherever they are in the UK!

A Kwickee™ can be as much as 5,000 characters (about a page and a half of text) and is therefore over 30 times larger than a 160 character SMS text message.

Kwickee enables content providers money for their content. See this.
