Does Blackberry Key2's mobile pay similar to Samsung Pay work in South Korea?

I'm very happy to see that Blackberry is coming back. Due to ease of using Samsung Pay on my Galaxy S7 edge in South Korea, I wanna know if I upgrade to Blackberry Key2 whether I would be able to use apps such as Samsung Pay or other apps like Android Pay or not. Thank you

BlackBerry's Mobile pay is just Android Pay, so if Android Pay works, then yes. In other words, there is no 'BlackBerry Mobile' pay... it's just Android Pay.
