That\u2019s why a recent move by <strong>KT (Korea\u2019s second-largest mobile carrier)<\/strong> got everyone\u2019s attention.<\/p>\n\n\n\n<p>After a <strong>security breach<\/strong>, KT began <strong>waiving contract termination penalties<\/strong>\u2014and a lot of customers took that as their chance to switch. In other words, <strong>KT users switch mobile carriers<\/strong> when the barriers to leaving suddenly disappear.

Another interesting detail: observers noted SK Telecom had a <strong>reinstatement policy<\/strong> for customers who had previously left SKT after its own breach, which may have encouraged some customers to \u201cgo back home.\u201d<\/p>\n\n\n\n<p>Translation: telecom competition isn\u2019t just about network quality. It\u2019s also about <strong>trust<\/strong>, brand reputation, and who offers the best deal when people are ready to move.

But the moment a company removes barriers\u2014like early termination fees\u2014customers suddenly have options.<\/p>\n\n\n\n<p>For KT, the immediate challenge is stopping the outflow. The <strong>KT users switch mobile carriers<\/strong> wave is a clear signal that trust can be lost fast\u2014and expensive to rebuild. The bigger challenge is rebuilding confidence.
