Is Global IoT SIM card work in South Korea?

I am thinking about using the sim card for a Particle IOT device (“BORON” is one I am trying)
Will this sim card can connect to Korean LTE network well?

Our SIMs will work in South Korea, though I cannot say for certain that the boron will since its not our product and I am not familiar with it. Always check the LTE bands supported by the device and in the country you are deploying in.
