Data pack for pre-paid not working

連合約到期日都冇
冇任何有用既information
終於等到CSL出iphone app!!
用這個app十分之方便查閱帳戶和設定.
Terrible App
Always undergoing maintenance
尽量改善吧
体验不好
Can’t make payment
Unable to select validation date wz CC payment, pls fix it.
Terrible UI
The UI/UX of this app is awful, making it nearly impossible to use. The layout is confusing, features are difficult to find, and the performance is consistently poor. I strongly recommend avoiding this app until significant improvements are made.
Slow
Long time to load. Very slow. Rubbish.
Seriously bad app.. it’s all ads and 1% functions
Seriously your update says UI/UX improvements.. adding more ads to Home Screen is an awesome improvement… lol.. Please make a working app. Also have a contrasting color pallet. You don’t use white on a grey background. Really basic stuff guys..no idea how apple approved the app
更新頻密
起碼每個月更新一次
Horrible!!!
Why is it that Chinese companies can’t produce and facilitate simple apps?? Why is it always so complicated to the point where it’s completely inefficient? I refuse to believe all of you are this stupid!!
worthless, pay bill doesn’t work, mostly ads
Pay bill feature stopped working with this update. Guess they don’t want bills paid. Check data usage doesn’t work. Only thing that seems to work is the many ads trying to get you to buy stuff.
Prepaid
why don't you have services for prepaid? as a tourist it would be very useful. sometimes tourist may keep the sim card for future use since instead of always have to get a new sim card upon arrival.
Bad update
I've got a family data plan with four SIM cards. After the last update I can see local data usage for my main number. THe other three show up. Why on earth do you release updates that are less functional. Annoyed.
Usage check not working!
Usage check was stopped from working for a long while already! Please check!
