Ratings and reviews

Users of older versions of this app are locked out of the app, and with the updates being more frequent than trains on the Tsuen Wan Line, this is an absolute nightmare to use.

A very stupid app. I have an extra data package and total 2. But the app cannot display the summerized data in the dashboard and I need to click into the detail page every time.

Everytime I want to top up through this app, it asks me to update to a new version in Google Play. Do the developers really understand software design with Android?

What's new

This version includes a number of UI/UX improvements as well as stability enhancement.
