Interactive SMS applications allow access to your applications by any mobile user, regardless of their device type, data plan subscription or level of technological "savvy".

The end user initiates the transaction by sending SMS message to a dedicated mobile number assigned to your company and the response is returned to them seconds later also via SMS.

 While SMS applications obviously lack the graphical richness of mobile applications, they are very frequently preferred by large enterprise customers because:

• SMS applications are accessible from any handset; no data plan subscription is required
• No handset configuration is needed
• In most markets, SMS messages are significantly cheaper than mobile data rates, with many mobile operators bundling a quantity of free messages into each user's subscription plan
• SMS applications are handset type independent; no handset-specific testing is required

The nexsites Platform provides a rich environment to build and deploy interactive SMS applications. By using a web site like metaphor of pages and links, your content manager creates an interactive SMS site with a structure similar to a website. Each "page" in the site results in a message sent to the handset. A page can contain static content, dynamically generated content and navigational links.

nexsites automatically provides session management and advanced interaction methods for interactive SMS applications. Without any special configuration or coding, interactive SMS applications built with nexsites automatically include:

• Navigation by menu item number
• Navigation by menu item keyword
• Fuzzy matching of misspelled keywords
• Session management and control including session expiration times
