Comparing with the first-generation analogue phones (1G) and second-generation GSM, CDMA and other digital phone (2G), it can quickly process a variety forms of media, for example, images, music, video streaming etc.，and provide a variety of information service including web browsing, conference calls and e-commerce. Up to the end of March 2011, Chinese mobile phone subscribers had exceeded 800 million in which 67 million 3G mobile phone users were included, China has entered the era of 3G communications. According to analyzing the communication technology trends of the 3G era, This paper research the current status of mobile phone meteorological information services and a variety of emerging mobile phone meteorological information service methods based on 3G communication technologies and explore the sustainable development path of me
