SMS Hiker Tracking Service
With the support of mobile service operators, the Communications Association of Hong Kong (CAHK) has launched the “50222 SMS Hiker Tracking Service” (“50222 Service”) to help search and rescue lost hikers. Hikers can use the service by sending short messages to a designated number “50222” to report periodically the unique numbers of Distance Posts they encounter along their hiking trails. This will help keep track of their positions. For example, sending the number “M001” means the hiker is at the first Distance Post of the MacLehose Trail. In any event that a hiker is lost, rescue parties can make use of the data stored at the system of “50222 Service” to improve the time and success rate of searching the lost hiker.
As long as you are connected to a Hong Kong Mobile Network, this service is free to use. You will not be charged per message sent. See the information sheets below for further details.
GPS Hiker Tracking Service
The “GPS Hiker Tracking Service” launched by CAHK facilitates a speedy and effective rescue. If you would like to use this service, please download and install the “Enjoy Hiking” app, which is developed by the Agriculture, Fisheries and Conservation Department (AFCD), onto your smartphone. Before starting your hiking trip, please launch the app and activate its “Hiker Tracking Service” function. The GPS system will then auto feed your tracking locations and record the relevant data at the service centre . The data can be retrieved and be used to facilitate rescue if any need arises from an emergency situation.
