Following the launch of voice search services by Chinese fixed-line telecom operators, the country's mobile communications operator China Unicom (CHU) has announced plans to launch its own voice navigation service 10191, which is expected to be put into commercial use before the opening of the 2008 Beijing Olympic Games.

Different from the voice service provided by fixed telecom operators that can only be used for information checks, China Unicom's voice navigation can also be used for car-based navigation and road navigation.

So far, China Unicom has opened the service on a trial basis for its CDMA users. China Unicom does not charge any fee for the service during the trial commercial use, but it may charge a monthly package or pre-selling standard time cards after it is formally launched. China Unicom says it will also launch air ticket and hotel reservation navigation service in major cities in the future.
