How do I enable ECG functionality on my husband's iPhone and Apple Watch?

the ECG function on my husbands phone and subsequently the ECG function on his watch say that it is unavailable. I am in Australia and I know that it functions on my own phone and watch. How do I enable this? I have tried everything available currently on the web.

Has the watch been set up, using the Family setup feature? In that case ECG is not available.

Which Apple Watch does you husband use, and has it been bought in a country where ECG is supported?

watchOS 26 - Feature Availability - Apple



To rule out a software issue, erase the watch and pair it again, setting it up as a new device. You will only lose your created Watch faces and may have to activate the cards in your Wallet app again.

Then check the ECG feature.

* The ECG app is not supported on Apple Watch SE or with Apple Watch For Your Kids.


Make sure that the ECG app is available in your country or region. Learn where the ECG app is available.


The ECG app can record your heartbeat and rhythm using the electrical heart sensor on Apple Watch Series 4 or later and all models of Apple Watch Ultra.
