## About KT

KT Corporation, operating under the mobile network code (MNC) 02 and mobile country code (MCC) 450, is one of South Korea's leading telecommunications providers. As a major player in the Asia & Middle East region, specifically within South Korea, KT has played a pivotal role in shaping the nation's digital landscape.
