as long as you have open the ECG app (activate and can use ECG functionality) while in Singapore, the activation flag will remain activated and sync together with your health data in icloud. Even if you reset the watch in Malaysia and re-pair it with your iphone also no problem.

haha, if for some reason ECG not working, can use the method used by other forumers to edit the activation flag also =p

Link, here you go

First time ECG must be activated while in ECG-enabled country..

MY serial number - in AW you wont be able to find ECG app, so you wont be able to "activate" it, simple as that.

Currently supported carrier in Malaysia: Digi, Celcom, Maxis

Read this to understand why it is able to work: Link

tldr; Apple can flip the switch anytime they want and this "exploit" will stop working. As long as you stay on the current proven working firmware, then the ECG will continue to work for you. As of now, iOS 13.4.1 and WatchOS 6.2.1 is still working (I had mine upgraded).

The account sold online already have the activation flag saved in icloud, so when it syncs with your Health app, it enables ECG functionality on your watch due to some changes by Apple.

lets say you use SG apple account and is at SG, how are you gonna "Activate" ? your MY firmware watch will not have ECG app, so there is no way to "activate" it.

You need to understand that the recent change by Apple is that: if your health data already contains the activation flag -> enable ECG on your watch no matter the region it is bought from.

when you sign in the "supplied" account, you will sync their health data to your iphone, when the "activation flag" is in your health data, the watch app will automatically show you the ECG app. then you are supposed to log out that account and sign back to your own account, so that the "activation flag" that is now on your iphone, will be synced to your icloud health data. Just be warned that Apple can anytime choose to revert back to previous implementation and the ECG app will be gone, I am not saying they will, but they could if they want to.

Hi, just want to share the misinformation regarding ECG activation on unsupported region's Apple Watch.

Read this link if you truly wants to understand the reason why we are able to activate ECG on unsupported region Apple Watch
Source: https://hiraku.tw/2020/02/6044/

TLDR:
During iOS 13.4 + WatchOS 6.2 development, Apple made a change to ignore Region checking if the Apple ID have already activated ECG before.


I highlighted the comments above because I want to point out that, even if you bought an AW from Malaysia and go to Singapore, there is no way for you to activate ECG because the ECG app is not even in your AW.

Edit: Forgot to point out that, Apple could just re-enable region checking in a future update on all Apple ID and Malaysia Region AW will lose the ECG functionality (I am saying it's possible, just not sure whether Apple will do it or not in the future). This is the reason why you will see sellers asking you not to update your iOS/WatchOS version because there is no guarantee what Apple will do in future software release.

I am currently on iOS 14 beta + WatchOS 7 beta and ECG functionality is still available on my Malaysia AW S5. But if I go into Health App, there is a new Health Checklist, it will list down ECG is not supported in my region, just saying that it's entire possible for Apple to do some simple checking and every Malaysia Apple Watch will lose ECG functionality even if your Apple ID contains the activation flag.

Wow, that's good to know actually. So you mean that you are able to see the ECG app in your MY AW when you are in SG? Because the "activation" of the ECG functionality actually happens when you open the app. It was previously not possible for Malaysia AW simply because we cannot find the app anywhere on our watch.

Here's some screenshot from iOS 14 beta:
In Health App, open your profile, select Health checklist:


This will list down all the features available to you:


EDIT: ECG functionality is still there on my AW though, not sure how Apple will handle this as we move nearer to iOS 14 release (somewhere Sept)

yeap, I just tried it and it works just like how it was previously. Take ECG reading on watch, after end, notification on iPhone

yeap, that was from beta 1 =) it no longer appears as unavailable after beta 2

EDIT: also, it was probably just a bug on the health app, I was still able to use my ECG while on beta 1 previously, so no biggie

hi, hardware wise all Series 4 and Series 5 supports ECG functionality. The app itself is hidden by region. However, since watchOS 6.2 (I think), as long as your iCloud Health contains the ECG activation flag, then the ECG app will appear on your watch regardless of region. Hope this answers your doubt.

I was using Autosleep app before sleep tracking was introduced and after trying out during AW beta time, I feel the Autosleep app is better at detecting sleep and less hassle (currently Apple Watch not able to automatically track your sleep, you need to toggle the Sleep button in your control centre to let your iPhone/Watch knows you are going to sleep).

For those with 2 Apple Watch (I use my Series 1 during bedtime), you can disable the Sleep Tracking on your S4/S5 by going into Watch app, Sleep, then select "Don't use this Watch for Sleep". Just a matter of preference, not saying one is better than the other.
