Free Wi-Fi connections will be extended to all MTR stations from next month.
Services on offer at 14 iCentres, which provide free internet access, will be available in paid areas of 84 stations from July 8. The service will cover neither trains nor platforms.
Each free connection session will last for 15 minutes, with mobile devices limited to five daily sessions.
The service is part of the MTR "Listening, Responding" program, which has launched various smartphone apps that keep passengers fully informed of the latest traffic news and information.
"Our customers tell us that communicating on their mobile devices is an important part of their daily lives. They would appreciate having free Wi-Fi services at all of our stations and we are responding to the request," chief executive Jay Walder said.
Sales and marketing senior manager Doris Chan Yuk-che said: "This service will benefit passengers who want to download a large- sized file or who do not have a data plan with their smartphones."
While using the service, passengers may also turn to the latest series of MTR emoticons to report or inform others of their location, such as "on the platform" or "I'll be waiting at Exit A."
The 12 customized MTR emoticons were co-designed by the company and WeChat.
Users of mobile devices may follow the MTR Wi-Fi hotspot account and enjoy a free game on the WeChat instant messaging platform when downloading emoticons.
