WAP

Most of today's mobile phones, smartphones and PDAs come with a built in WAP browser (WAP, incidentally, stands for Wireless Application Protocol). With a WAP browser, you can access dedicated WAP pages while on the move.As WAP phones have smaller, often black-and-white screens, content is often fairly basic, and are often text-based pages without any images. The upside of this is that the pages are quite efficient and downloaded fairly quickly, but the downside is that WAP can be a fairly bland experience when compared with surfing the Internet from a web browser. WAP is supplied as a service by most mobile phone operators. Recently, GPRS Wap has become available, allowing faster browsing via an always-on connection. With GPRS, you are billed by the amount of data you send, where standard GSM circuit-switched WAP found on most WAP mobile phones, is billed by the length of time you are online looking at WAP content. Some UK operators, notably o2 online, offer an inclusive GPRS WAP allowance.
