ST WiFi Calling

ST WiFi Calling
Call Hong Kong from overseas when connected to WiFi

ST WiFi Calling saves roaming charges for calls to any Hong Kong numbers and for receiving calls from anywhere in the world.

The other party of the call does not have to be a SmarTone subscriber nor does he need to install the ST WiFi Calling app. Therefore, you can enjoy the service with minimum hassle.

What’s more, when you are in Hong Kong and places where mobile signal is weak or suffers from interference, you can still make and receive calls with ST WiFi Calling and stay fully connected.
