RM520NGL 5G module - Compatible with Korean communication companies

There are three major communication companies in South Korea, SKT,KT and LGU+. What I want to know is whether the RM520NGL 5G module is compatible with all of them?

Dear @shiyuancheng
What do you mean of compatible with all of them? Register or others?
It has carrier certifications as below:

Thank you for your answer.!!

I am currently using a KT operator 5G SIM card. Right now, I can only search for LTE networks, but not 5G. Do I need to configure any additional settings, or could there be a wiring issue with my 5G-M2-EVB-KIT (as shown in the attachment)?
