hi bro, right now using apple watch as a standalone device is not possible. we have to pair it with an iPhone and all the data will be shared between the devices. Currently checking with one user where he is trying to configure jio cellular for apple watch to use it for his kid. a standalone device that uses cellular feature and setup as family member option in watch app.
But encountered several issues in the past few weeks of cellular automatically deregistered and have to register again.
So kindly wait, this type of feature may take some time to come to india and official info is not yet available from network providers.
If your parent have their iPhone then its possible to setup apple watch and use the health sharing feature with your apple id.
