WAP is the abbreviation for Wireless Application Protocol, a secure specification that allows users to access information instantly via handheld wireless devices such as mobile phones, pagers, two-way radios, smartphones and communicators.

Web sms allows users to send WAP bookmarks. In simple terms you sms a web site url to a person that have access to a WAP enabled phone. They will receive a message and could follow the link from the WAP bookmark in their "inbox" and surf the appropriate web site on their mobile phone.

Please ensure that the receipients of the WAP bookmarks have WAP enabled phones as all messages sent will be charged for.

What is the difference between a WAP bookmark and MMS?
Multi-media messaging takes place when you send Audio, Audio video, Animation/slide, Video, Text or Static Images. With WAP bookmarking we send a web site URL which the receipient have to visit. It is still cheaper than MMS.
