Unicom now uses the data services are a little access, the whole network service. This is a whole new business model compared with the previous provinces and the government. This is more conducive to the whole marketing, brand promotion and the whole network of uniform service standards. Unicom provides technical support and business guidance to developers, as well as to all content providers, and attracts powerful developers to join operations to help small content providers develop their business.
