Best eSIM for Greece in 2026: unlimited data, real prices and what to check
Key facts
- VoaSim's eSIM for Greece starts at USD 18.90 for 5 days with truly unlimited data, no cap and no throttling.
- It connects automatically to Cosmote, Vodafone and Nova, covering Athens and the main islands on 4G and, where available, 5G.
- Validity starts at first connection in Greece, so you can install the QR code at home days before flying.
- Greece is included in the Europe plan of 50 countries, so side trips to Turkey, Italy or Cyprus need no new eSIM.
- For stays over 90 days or when you need a Greek phone number, a local prepaid SIM is the better option.
See the exact price for your dates
Greece is a maps-and-ferry-schedules kind of trip. You will look up bus times in Athens, check the last boat out of Mykonos, upload photos from a Santorini rooftop and call your family over WhatsApp from Crete. All of that runs on data, and that is exactly where most travelers pick the wrong plan.
This guide compares how eSIMs work in Greece, shows the exact VoaSim prices by trip length, and is honest about when another option beats us.
What "best" actually means for a Greece trip
There is no single best eSIM for everyone. There is a best eSIM for your usage. Three things decide it:
- How much data you burn. If you stream, upload video, tether a laptop occasionally or travel with heavy Google Maps use, a per-GB package becomes a math problem you keep re-solving mid-trip. An unlimited plan removes that.
- How long you stay. A 4-day Athens stopover and a 3-week island-hop have different cost curves. Daily price drops sharply with longer plans.
- How much friction you tolerate. A local Greek SIM is cheap but costs you airport time, passport registration and your own number leaving the phone.
VoaSim is built for the middle case that covers most travelers: a week or two in Greece, heavy phone use, zero interest in managing gigabytes. One price per duration, the same for Greece as for anywhere else we cover. You can check your exact cost in the price simulator.

Coverage in Greece: networks, islands and ferries
The eSIM connects automatically to local Greek networks — Cosmote, Vodafone and Nova — and picks whatever is strongest where you stand. You do not choose a carrier or type an APN; it happens on first connection.
What to expect on the ground:
- Athens, Thessaloniki and the main islands (Santorini, Mykonos, Crete, Rhodes) have solid 4G, with 5G available in places. We do not promise 5G — it depends on the network and your phone.
- Ferry crossings are the weak point. Signal holds near the coast and in ports, then drops in open water between islands. Download your maps, tickets and playlists before boarding.
- Cruises work the same way: on land at each port, not at sea. Ship Wi-Fi is a separate purchase.
- Remote beaches and mountain villages can be patchy for any carrier, local SIM included.
Note that Greece is inside our Europe plan of 50 countries, so a hop to Turkey, Italy or Cyprus runs on the same eSIM with no new purchase.

Unlimited vs per-GB eSIMs: the honest comparison
Most eSIM brands sell Greece by the gigabyte through an app: Airalo, Nomad, Saily, Ubigi, Yesim, GigSky, Alosim, Jetpac, MobiMatter and others. Holafly sells unlimited-style plans with usage conditions written in its terms. Prices and rules change often, so check each official site before buying — we will not quote their numbers here.
The structural difference:
- Per-GB plans are excellent when your use is genuinely light — hotel Wi-Fi most of the day, a few maps lookups, messaging only. You pay for a small bundle and you are done. The risk is the top-up spiral on day four.
- VoaSim's unlimited has no data cap, no speed throttling and no hidden fair-use clause. Cost is fixed the day you buy. The trade-off: it is data only, with no phone number or traditional voice calls, and we do not promise hotspot — if you plan to tether, ask support first.

When a local SIM or carrier roaming is the better pick
Fair is fair. Three cases where you should not buy our eSIM:
- Very long stays. If you are living in Greece for months, a Greek prepaid SIM from Cosmote, Vodafone or Nova gives you a local number, local rates and the option to keep renewing. We cap at 90 days per eSIM. Expect passport registration and a trip to a shop.
- You truly need a phone number in Greece. Some rentals, delivery apps and bank verifications want a local mobile number. A data eSIM does not give you one.
- Your carrier already bundles it. Some T-Mobile, EE, Vodafone, Three, Telstra, Rogers or Google Fi plans include international data in Europe at no extra daily charge. Open your carrier app and check the current rate for Greece before you buy anything. If it is included and the speed is acceptable, use it. Our roaming guide explains what to look for.
An older phone without eSIM support also rules us out — we do not sell physical SIM cards.
Buy, install and land connected
The QR code arrives by email within minutes of payment, plus a WhatsApp heads-up if you left a number at checkout. Install it at home, before you fly.
- Check compatibility. Dial *#06#: if an EID appears, your phone supports eSIM. Works on iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer and most phones from 2020 on. Carrier-locked phones must be unlocked first.
- Scan the QR at home using our step-by-step iPhone and Android guide. Then leave the eSIM line switched off. On Android, do not enable its mobile data before the trip.
- Validity starts at first connection in Greece, not at purchase. So installing early costs you nothing.
- On landing at Athens or your island airport, turn the eSIM line on and turn off data roaming for your home carrier. Your physical SIM and your number keep working, so WhatsApp stays on your number.
