Can I make traditional calls or send SMS with my EastESIM in Korea?

Most EastESIM plans for destinations like South Korea are primarily data-focused, offering robust internet connectivity through carriers like SK Telecom or KT. While direct traditional calls or SMS are generally not included, you can effortlessly use popular internet-based communication apps such as WhatsApp, Line, KakaoTalk (essential in Korea), FaceTime, or Skype for both calls and messages. For those needing a local Korean phone number, many VoIP services or virtual number apps can provide this functionality, integrating seamlessly with your data-rich eSIM connection.
