A WAP browser provides all of the basic services of a computer-based web browser but simplified to operate within the restrictions of a mobile phone, such as its smaller view screen. Users can connect to WAP sites: websites written in, or dynamically converted to, WML (Wireless Markup Language) and accessed via the WAP browser.

Your personal home page will contain links to WAP sites, Mobi sites, etc.  These sites not only load faster, they use significantly less data than a standard web page.  Unless you are on an unlimited data plan, this is a huge data saver.  Plus, you get to choose up to 12 of your own links to add to the 12 that are included.
