I do know the remote connection feature requires the Galaxy Wearables app and that the phone and the watch be signed into the same Samsung account. https://www.samsung.com/us/support/answer/ANS00061431/
thanks for answer, but on iPhones Samsung Watch app there are no remote connection settings and settings for WiFi since. And watch and phone app have the same account.
even Samsung support can't tell what functionality works with others phones.
so this is my last Samsung wearable.
