Update: Still works for iOS 13.5 + watch OS 6.2.5 public release
I can provide clean account to activate your Apple Watch’s ECG feature, please contact @hiraku_dev on Twitter.
Few months ago, I posted a tutorial about how to enable ECG feature of Apple Watch (oversea model). The restriction is: you must have an Apple Watch which is bought from ECG feature enabled region. However, Apple made a mistake on iOS 13.4 beta 2 and watchOS 6.2 beta 2, ANY Apple Watch S4 or S5 can enable ECG feature now!
iOS 11.5 + watchOS 6.2.5 正式版依然可用。
之前在 ECG 自己開通教學 裡面，大部分人遇到的最大瓶頸就是，自己所在國家 / 地區買的手錶不支援 ECG 功能，導致無法使用這個方法開通。不過由於 Apple 在 iOS 13.4 beta 2 跟 watchOS 6.2 beta 2 出包了，所以現在任何國家的手錶都可以使用！
Before you start to do anything, please read the following descriptions, they are very important.
Please upgrade to iOS 13.5 + watchOS 6.2.5 first, because with these versions, you can activate ECG regardless the region of your device!
English version here
無論如何，請先升級到 iOS 13.5 + watchOS 6.2.5，因為這個版本組合可以「無視地區」開啟 ECG 功能！
在開始本教學之前，有幾點非常重要，請大家看清楚。
