Do I need a local ID number, such as a Korean Alien Registration Card, to activate my EastESIM?

No, you absolutely do not! This is one of the primary advantages of choosing EastESIM for your travels to countries like South Korea. Purchasing a local physical SIM card from carriers like SK Telecom, KT, or LG U+ often requires foreigners to have a local Alien Registration Card (ARC) or go through a complex registration process at a physical store, which can be time-consuming and confusing. Our EastESIM is a roaming data plan, designed specifically for international travelers, meaning it requires no local ID or complicated paperwork. You can activate it easily and be connected to high-speed data as soon as you land in Seoul or Busan.
