Our top 3 picks for Greece
We evaluated 7 eSIM plans available for Greece, comparing them on verified pricing, network coverage, top-up availability, and app quality. Five stood out.
HelloRoam
Best Value
$7.34
5 GB / 30 days
Pros: Lowest price per GB, fast activation, Greece coverage on Wind and Vodafone. Cons: Newer brand, smaller community than Airalo.
HelloRoam ranks first for Greece because it roams on both Wind Hellas and Vodafone Greece 5G, the pair that keeps Santorini's Fira and Oia, Mykonos Town, and Heraklion on 5G while a single-network plan drops to 3G on the smaller Cyclades. Wind is the primary eSIM network and covers Athens International Airport (ATH), Athens city center, Piraeus port, Thessaloniki, and the main Aegean island hubs including Heraklion (Crete), Mykonos, and Santorini on 5G. Vodafone Greece provides an alternative 5G network with strong coverage in the same major destinations and slightly better performance in northern Greece near Thessaloniki.
Coverage analysis
Wind Hellas delivers 5G across Athens' Syntagma, Monastiraki, and Kolonaki districts, along the Attica coastal road to Cape Sounion, and in Thessaloniki's Aristotelous Square area. Vodafone Greece matches Wind in Athens and outperforms it on the E75 highway corridor toward Thessaloniki. Santorini's Fira and Oia maintain consistent 5G.
Mykonos Town and the port are well-covered. Honest limitation: ferry crossings between islands (Piraeus to Mykonos, Piraeus to Heraklion) drop signal for 60 to 90 minutes in open-sea stretches, and small islands like Folegandros, Sikinos, and Donoussa have 3G only from both carriers.
Activation
Install your e-sim QR code before departure and enable it after landing at Athens International (ATH). Thessaloniki's airport (SKG) also connects on arrival. Wind and Vodafone both register new eSIM profiles automatically once the line is switched on. iPhone XS or newer and Android devices from 2019 support Greece's 5G Band 3 and Band 28 frequencies.
Greece is in the EU, so check the plan page for the cross-border terms that apply to your profile.
Data usage tips
Greece travel data needs are moderate. Google Maps covers Athens' metro system (OASA), Thessaloniki buses, and ferry routes clearly, using 50 to 80 MB per hour of active navigation. Museum audio guides for the Acropolis, National Archaeological Museum, and Delphi each use 100 to 200 MB.
Instagram and social media from Santorini's photogenic caldera views runs 300 to 500 MB per day for active posters. Offline Google Maps download for Crete covers the entire island in 250 MB. A 5 GB plan covers 2 weeks of standard tourist use comfortably.
eSIM plan pricing in Greece
Entry-level: Greece 1 GB / 7 days at $2.21 on Wind or Vodafone 5G covers a 4-day Athens city break. The 2 GB per day plan costs $2.21 and suits island-hopping, with a fair-use speed reduction once the daily allowance is spent. Mid-tier: Greece 5 GB / 30 days at $7.34 ($1.47/GB) handles most 2-week itineraries.
Value pick: Greece 10 GB / 30 days at $12.62 ($1.26/GB) for remote workers or hotspot sharers. Extended stays: 20 GB at $32.00 and 50 GB at $44.29, which is $0.89/GB across the 7 plans verified. Verdict: the best eSIM for Greece is HelloRoam at $7.34 for 5 GB on Wind and Vodafone 5G, against Airalo at $12.00.
Listed HelloRoam prices for this destination also include $3.10.
