This URL is the cancellation page — you do not have to hunt through settings
Go to the KKBOX cancellation page
https://mykkid.kkbox.com/
Cancelling does not cut you off immediately. You keep access until the end of the period you already paid for, so if you have decided not to renew you can cancel straight away without losing anything.
You cannot cancel on the day before or the day of the charge. KKBOX suggests doing it three days before the expected billing date, or the day after. Land on those two days and you get charged for another period.
Subscriptions through Chunghwa Telecom, Taiwan Mobile and other carriers have to be cancelled with the carrier — not here.
Days remaining on the account can still be used after cancelling, but they are not refunded.
The same goes for App Store subscriptions on iPhone: cancel in iOS under “Settings → Apple ID → Subscriptions”.
Prices verified , with the official page as the final word. Plans and availability vary by region; these are the official Taiwan prices.
People who forget to cancel are not careless — the moment you decide and the moment you are charged are a whole month apart. Add LapseWatch on LINE and send “KKBOX 12/25” to record it. No install, no signup.
Want to see the whole picture? Add up a year of subscriptions (in Traditional Chinese); if you work at a computer there is also a Chrome extension that keeps everything on your own machine.
Interfaces change. Always treat the official page as the final word.
