China Unicom announced that it has stopped accepting content from its service provider (SP) Shanghai Huiyang Technology Company because Huiyang was providing pornographic content to mobile phone users.

According to Zhou Xiaoping, deputy general manager of the Value-Added Services Department of China Unicom, the management at China Unicom is very concerned with pornography issues and has ordered concerned departments to seriously deal with the matter.

Huiyang's alleged pornographic content was included in a type of mobile dictionary that users could download and use on their mobile phones.

China Unicom usually signs "Internet Access Safety and Obligation Guarantee" and "Mobile Value-added Service Cooperation" contracts with each of its SPs and CPs (Content Providers) as a precondition for their cooperation. The contracts state that both parties promise not to release any illegal information.
