No Sim in another country

No Sim in another country

Hey all,

I recently bought a second-hand iPhone XR in Germany (Thie.com) and it works perfectly in EU and even in Korea where I am now. The problem is when I insert a Korean SIM card provided by KT, the phone does not recognise the signal and keeps showing 'No Sim'.

So far, I have tried almost everything I can do from my side. I would ask here whether it would be possible that the company who sold the phone might have fixed the phone not completely or somehow imperfectly that it only exclusively works with German SIM card. Is it possible?

Thank you for your comments and ideas in advance.
