Her response is incorrect. I have a Note 3 N900T (t-mobile) running the rom listed in my signature. The rom is a Note 3 N9005 (International version of the Note 3) and I have the Safety Assistance now.
Here is a stock International version...

Now call the rep back and tell her to learn about the products that she represents
I'm sure a Dev could probably rip this out and make a patch to add it to any Note 3.
I would love to find that Safety Assistance for my Sprint Note 3. It is also listed for the Gear 2 by triple tapping the home key, but I don't have that either. As a recent pacemaker recipient, this could be a lifesaver for me.
