Photo taken on Sunday, September 5, 2010 shows a cell phone SIM card sales outlet where cell phone users don't need to show their ID cards to buy SIM cards in Nanchang city of southeast China's Jiangxi Province. China's real-name cell phone registration system, which started September 1st, asks mobile phone users to submit their personal information when they purchase a new SIM card. However, the anonymous cell phone SIM cards can still be bought from some small-scale dealers in China. [Photo: Xinhuanet]
