eSIM vs local SIM in Greece
Both options give you local data in Greece, but they work differently. The right choice depends on how you travel and how much setup friction you can tolerate.
| Factor | Travel eSIM | Local SIM card |
|---|---|---|
| Price (7 days, 5 GB) | $1.14 | $15 avg |
| Where to buy | Online, before you leave | Airport, store, or online |
| Activation time | Under 2 minutes | 5 – 60 minutes |
| Passport required | No | Yes (mandatory) |
| Phone number included | Data only | Yes, local number |
| Hotspot tethering | Yes (HelloRoam, Saily) | Yes (most plans) |
| Works on dual SIM | Yes, alongside home SIM | Replaces your home SIM |
| 5G access | Yes (HelloRoam) | Varies by local carrier |
Verdict: An eSIM costs less than a local SIM for a typical 7-day trip to Greece and activates before you land. It is the faster, lower-friction option for most travelers. Local SIM registration in Greece requires a passport, adding 15 to 60 minutes at the point of purchase. eSIMs skip this entirely.

How to set up an eSIM in Greece
eSIM activation works the same way across all carriers. The process takes under 5 minutes on a compatible phone.
Confirm eSIM compatibility
Your phone must support eSIM. Most phones released after 2020 do, including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Check Settings for an eSIM or digital SIM option.
Check your phone is carrier-unlocked
Some carriers lock phones to their network. If you bought your phone on contract or from a carrier store, contact them to unlock it before your trip. eSIMs from third-party providers will not work on a locked device.
Purchase your Greece eSIM plan 1-30 days before your trip
Buy from HelloRoam, Airalo, Holafly, or another provider listed above. You can purchase 1 to 30 days before departure. Choose a plan that covers your intended stay. You receive a QR code by email within minutes of purchase.
Scan the QR code
Go to Settings > Mobile / Cellular > Add eSIM (or Add Data Plan). Point your camera at the QR code. The eSIM profile installs in about 60 seconds.
Activate on arrival in Greece
Most plans activate when you land. Set the eSIM as your primary data line in Settings. Turn off data roaming on your home SIM to avoid unexpected charges. Run a speed test to confirm you are connected.
eSIM notes for Greece
Greece has three carriers: Cosmote (largest, best island coverage), Vodafone Greece, and Wind Hellas. Athens Airport (ATH) has Cosmote and Vodafone stores in arrivals. As an EU member, any EU SIM card roams in Greece at domestic rates. Cosmote covers more Greek islands than its competitors.
Athens has strong 4G from Cosmote and Vodafone across the city and the Metro system in most stations. Santorini and Mykonos have excellent coverage in the main towns. The caldera rim villages on Santorini all get signal. Crete: Heraklion, Chania, and Rethymno are well covered. The Samaria Gorge hike has Cosmote signal at the top in Omalos and at the bottom in Agia Roumeli but nothing in the gorge itself. Naxos has coverage in Hora. Rhodes city and the west coast resorts are fully covered. Remote northern Aegean islands like Samothrace and Limnos have Cosmote coverage in main towns only. Ferry crossings between islands will lose signal in the open Aegean.
Local Cosmote SIM is easy to buy in Athens. eSIM is the top choice for island-hopping itineraries where buying a local SIM is less practical and EU roaming covers connections to other European destinations.
Things to know before you buy

- Most international eSIM providers do not support calls or SMS in Greece. Keep your home SIM active in dual-SIM mode for those functions.
