Mobile instant messaging

Mobile Instant Messaging (MIM) is a presence enabled messaging service that aims to transpose the Internet desktop messaging such as ICQ or MSN experience to the usage scenario of being connected via a mobile/cellular device. While several of the core ideas of the desktop IM experience and functionality on one hand apply to a connected mobile device, others do not: Users usually only look at their phone's screen—presence status changes might occur under different circumstances as happens at the desktop, and several functional limits exist based on the fact that the vast majority of mobile communication devices are chosen by their users to fit into the palm of their hand.
