eSIM Saily pour Japan en 2026

No Japanese network is named: Saily has not published which operators it uses in Japan, so its radio side is unknown rather than a sign of poor coverage; the table above is where to check the practical plan details. Its large range makes sizing the real decision, with the risk of buying more data than a fortnight needs. Saily also does not say whether top-up is available, so check whether an exhausted plan can be extended or must be rebought before purchase.
