EastESIM prides itself on partnering with leading local carriers throughout Asia to deliver superior speed and coverage. For instance, in South Korea, you'll connect to SK Telecom or KT; in Thailand, it's often AIS or TrueMove H; and in Vietnam, you'll find strong signals with Viettel or Mobifone. Our plans are designed to automatically select the strongest available 4G/5G signal, ensuring you stay connected whether you're in a major city like Tokyo or a more remote island destination in the Philippines.
