The pricing ladder spans from 1GB at $2.21 ($2.21/GB) to 20GB at $32 ($1.60/GB). Best per-GB value sits at 10GB for $12.62 ($1.26/GB), our recommended tier for most Greece travelers. Holafly adds an unlimited daily option from $2.99/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 5G speed until the data cap is reached, with no mid-plan throttling.

Carrier Partnerships
Greece operates 2 mobile networks: Wind (5G), Vodafone (5G). Cosmote (OTE) serves as the primary routing partner for travel eSIMs in this market. All five ranked providers maintain routing agreements with Cosmote (OTE). Some providers additionally route through Vodafone as a fallback when Cosmote (OTE)'s signal weakens.
Cosmote (OTE) publishes 5G across Greece, and every ranked provider attaches to it rather than to a network of its own. Two carriers give Greece travelers basic redundancy. Vodafone supplements Cosmote (OTE)'s coverage in areas where the primary signal is weak.
Cosmote (OTE)'s 5G network handles all travel eSIM traffic in Greece. Provider differentiation comes from plan pricing ($0.89/GB entry), app features, and support channels rather than carrier routing choices.
