Here's a breakdown of how the SIM card replacement process works and the steps customers can take to swap their SIM cards safely:
Hack Implications for SIM Card Swaps

Swapping Your SIM Card
Follow these steps to change your SIM card in Seoul or other locations:
- Eligibility Check: All SK Telecom customers are eligible for a free SIM card swap.
- Locate a Store: Customers can visit any of the approximately 4,600 T World stores or airport roaming centers. To minimize waiting time, utilize the online reservation system [4][5].
- Reservation System: Reserve an appointment online through the Care TWorld homepage or the TWorld website to streamline the process and reduce waiting time [4][5].
- Reimbursement: If a customer decides to replace their SIM card independently, SK Telecom will reimburse them for the cost [4].
