UniqU was previously known as OZchat and is notable for being the worlds first social network developed for mobile phones. This product became the number one service on the Vodafone Live! consumer platform in Australia for many years. It was also the first product in Australia and one of the first globally to use a process known as Direct Carrier Billing (DCB). DCB is where a product or service is charged directly to the customers mobile phone account.
