Saily eSIM Plans for South Korea

Saily has not published which operators it uses in South Korea, so the radio side is unknown rather than bad; the table above is where to check the allowances and validity. Its large range of plans makes sizing the real decision, with the risk of buying more data than a fortnight actually needs. Saily also does not say whether an exhausted plan can be extended with a top-up, so confirm that before relying on one plan for a longer trip.
