MXit (pronounced "mix it") is a mobile instant messenging application developed in South Africa that runs on GPRS/3G mobile phones with java support. It allows the user to send and receive text messages to and from PCs that are connected to the Internet and other phones running MXit. These messages are sent and received via the mobile Internet, rather than with standard SMS technology.
The user can also exchange messages with online chat communities like MSN Messenger, ICQ, and Jabber. Messages are limited to 2 000 characters. Because messages are billed by the amount of data sent, they are much cheaper to send than traditional SMS messages.
MXit claims to have a registered userbase of two million and about five million log-ons per day. The application is distributed internationally, but the bulk of its userbase are South African teenagers.
