eSIM Roamless pour Greece en 2026

Cosmote is the sole operator Roamless names for Greece, so the radio choice is settled before you select a plan: the differences within its large range are allowance and validity, not which named network to use. Roamless lists service up to 5G, a ceiling rather than a promise about the handset’s connection. It has not published where Greek traffic breaks out, so local delay and IP location remain unspecified. Top-up is stated as supported, allowing an exhausted plan to be extended rather than necessarily rebought.
