Does my smartphone require unlocking to use an eSIMAdventures plan in Seoul?

Yes, to seamlessly use an eSIMAdventures plan in Seoul, your smartphone must be unlocked by your home carrier. While most modern devices support eSIM technology, an unlocked phone is crucial for it to accept and operate with a new network profile from an international provider. Always confirm your phone's unlocked status and eSIM compatibility before you purchase your plan. This ensures a smooth connection to South Korea's robust networks like SK Telecom or KT upon your arrival.
