China Unicom (CHU) says it has launched CDMA international data roaming services for Chinese travelers visiting South Korea.

The new service is only available to the post-payment CDMA users of China Unicom and it can be automatically opened after the users submit an application at China Unicom's business halls or call its service number. The fee for the new service is CNY100 for every 1M of data flow.

China Unicom says so far that it has launched the service in the two countries of the U.S. and South Korea. But it has not disclosed the fee for the service in America.
