How hard is it to cancel KT (Korea Telecom)?

KT allows cancellation of mobile services online (via MyPage > Mobile Cancellation, with a follow-up call from a consultant to confirm), by phone (100), in-person at KT Plaza, or by mail/fax — account holder identity verification is required for all channels. Home/internet products can be cancelled online (reservation system), by phone at 100, in-person, or by mail, but the online process is a reservation that requires a callback from a KT agent before the cancellation is finalised. No explicit advance notice period is published; outstanding charges, early termination fees, and device installments must be settled before cancellation is processed. Unused pre-paid balances are refunded upon request (2 business days after application) via MyPage or KT Plaza visit; customers who port their number to another carrier must wait until the end of the month following cancellation to claim any refund.

Scope & fairness

This is the Documented-Policy tier: it measures how clearly the cancellation policy is published (cited, dated facts), not the behavioural experience of cancelling (Verified-Flow audit pending). Every company is scored on the same five dimensions with the same published weights — scores cannot be bought or removed. It is opinion grounded in disclosed facts, and not legal advice.
