eSIM Firsty pour South Korea en 2026

Firsty has not published which operators it uses in South Korea, so its radio network options are unknown rather than necessarily limited; the table above is the practical check. It lists 5G as the fastest technology, stated as a ceiling rather than a guarantee. Its breakout location is also not stated, so neither local latency nor IP location should be assumed. A large range of plans makes data sizing the main choice, with the risk of buying more than a fortnight needs. Tethering can get a laptop online, and top-up can extend an exhausted plan.
