eSIM Firsty pour Greece en 2026

A large range of plans makes sizing the real decision for Greece: the risk is buying more data than a fortnight actually needs. Firsty has not published which Greek operators it uses, so the radio side is unknown rather than bad, and it has not stated where traffic breaks out, leaving local delay and apparent IP location uncertain. 5G is the fastest technology it lists, not a promise for every handset or street. Top-up is supported, so an exhausted plan can be extended rather than rebought.
