Does my phone support eSIM in South Korea?

If your phone supports eSIM (iPhone XS+, Pixel 3+, Samsung S20+, etc.), it will work in South Korea. Our eSIMs use local carrier networks for the best coverage.

When does the data plan start?

Your data plan activates when you first connect to a network in South Korea. You can install the eSIM before your trip -- it won't start counting until you arrive and connect.

Can I receive calls and texts with the eSIM?

Our eSIM plans are data-only. You can keep your regular SIM active for calls and texts while using the eSIM for mobile data. You can also use VoIP apps like WhatsApp, FaceTime, or Zoom for calls.

What network will I connect to?

Your eSIM will automatically connect to the best available network in South Korea. We partner with major local carriers for reliable 4G/LTE coverage.

We offer refunds for unused eSIMs. Once an eSIM has been activated (connected to a network), it cannot be refunded. Contact our support team for assistance.

Travel Tips

South Korea has arguably the best mobile coverage in the world. You will have fast connectivity virtually everywhere, including in subways and elevators. Google Maps has limited functionality in Korea, so download KakaoMap or Naver Map instead. T-money transit cards work alongside your eSIM. Budget 2-3GB per week for standard use, more if streaming.
