A mobile portal is an Internet gateway that enables mobile devices to connect remotely with an enterprise intranet or extranet, typically via a Web browser interface. Consumer-oriented mobile portals provide access to mobile services and content using channels such as SMS, a microbrowser such as WAP, i-mode and voice. Consumer mobile portals aggregate content from many sources and may offer personalized services and content to mobile users — for example, unified messaging, news, search facilities, directories and m-commerce transactions.
