how to synch health data sleep app between Iphone and stand-alone iwatch? my iphone has a different Apple ID than my iwatch. Tmobile said that my iwatch need to have its own apple ID in order for it to work as a stand alone device with its own phone number. I am trying to get my iwatch to transfer (synch) my heart data to my iphone health app. Please advice.

The Apple Account has to be the same as the one used on the paired iPhone, otherwise your Heath data will not sync.

...

  • Make sure you have an eligible mobile data plan with a supported network provider. Your iPhone and Apple Watch must use the same network provider,* and you must be within your provider’s network when you set up mobile on your watch.

If you set up the Apple Watch for a family member who has no own iPhone, some health features are not available:

...

The following features and apps are not available: Medications, respiratory rate, irregular heart rhythm notifications, ECG, AFib History, Cycle Tracking, Sleep, Wrist Temperature, Blood Oxygen, Walking Steadiness, Audiobooks, Remote, News, Shortcuts, and the double tap gesture.

I m still unable to set up the stand-alone iwatch to synch up to my iphone health app. when both devices used the same apple ID, the watch loose its stand-alone number. The iphone kept overriding the iwatch number. I want to be able to use my watch to call and text with its own number even when the phone is not near by. Is this setup possible?
