I highly recommend buying an eSIM from a third-party provider because it will avoid facing complicated buying processes. Even though Gigago, the most reliable eSIM provider, does not offer eSIM plans for this carrier, you can also use our SKT SIM services.
For South Korea, Gigago offers multiple data plan options, starting from 1GB/day for 3 days with $5.90 . What is great about Gigago South Korea eSIM is that its plans’ costs are diversifying, varying between $5.90 – $106.50 .
