@Sk2020: Due to software and hardware variances that exist in our devices from region to region, you may experience compatibility issues if you use a device in Israel that was intended for use in Austria. The LTE variant of the Galaxy Watch Active 2 features an eSIM, so rather than a region lock you may find that you're only able to purchase it on a certain Austrian network, and the watch will then be locked to that network. For your peace of mind you might be better off exploring your options via networks in your home region. I hope this helps.
