eSIM Saily pour Greece en 2026

A large range of plans makes data sizing the main decision: the risk is buying more data than a fortnight actually needs. Saily has not published which operators it uses in Greece, so the radio side is unknown rather than bad; the available allowances and validity are the things to check in the table above. It also does not say whether an exhausted plan can be extended by topping up, so check this before buying if running out mid-trip would be a problem.
