don't use their insurance. Recently I was in Istanbul and the insurance didn't activate. Their app did not register me as in Turkey. All permissions were ok, Google Maps worked and I purchased a cappuccino with the Revolut physical card in Istanbul. Still, according to them I was not in Istanbul and there was some problem on my end.

So, I was uninsured. Imagine if this happens when you are in the US and you get sick. This is serious stuff, it's just too risky to let them play with it.
