Cheap eSIM for Greece: the real cost per day (and the cap trap to avoid)
Key facts
- A VoaSim eSIM for Greece costs USD 18.90 for 5 days and drops to USD 1.78 per day on the 60-day plan.
- Data is truly unlimited: no GB cap, no throttling and no hidden fair-use policy, so there are no top-ups mid-trip.
- Adding a second eSIM to the same order gets an extra 10% off — useful for couples island-hopping.
- Your days start at the first connection in Greece, so install at home and keep the line off until you land.
- Coverage runs on Cosmote, Vodafone and Nova in Athens, Santorini, Mykonos, Crete and Rhodes, but drops in open water between islands.
See the exact price for your dates
"Cheap" only means something when you know what you get for the money. Most eSIM deals for Greece look low because they sell you a few gigabytes. Then Google Maps in Plaka, ferry tickets on your phone and a couple of Reels on the Santorini caldera eat the bundle, and you top up twice.
This page shows the real cost per day of a VoaSim eSIM in Greece, why a longer plan is cheaper per day, and how to get an extra 10% off when two people travel together.
VoaSim price for Greece: cost per day by plan length
One price per duration, the same for Greece and every other covered destination. Today's prices already include the 15% promo:
| Plan | Price | Cost per day |
|---|---|---|
| 5 days | USD 18.90 | USD 3.78 |
| 7 days | USD 23.90 | USD 3.41 |
| 10 days | USD 30.90 | USD 3.09 |
| 15 days | USD 42.90 | USD 2.86 |
| 30 days | USD 61.90 | USD 2.06 |
| 60 days | USD 106.90 | USD 1.78 |
The longer the plan, the lower the daily rate: USD 1.78/day is the floor, on the 60-day eSIM. Trips of 1 to 4 days pay the 5-day package. Maximum is 90 days per eSIM. Check your exact dates in the price simulator.
The cap trap: why "cheap" GB plans get expensive in Greece
Greece is a heavy-data country whether you plan it or not. You navigate the Athens metro, you check ferry schedules, you upload photos from Oia, you video-call home from a taverna. Maps running for hours and HD video are the two biggest data burners on any trip.
Brands that sell by the gigabyte (Airalo, Nomad, Ubigi, Saily, Maya Mobile and others) can be excellent value if you are a light user who mostly stays on hotel Wi-Fi. The risk is the second purchase: when the bundle ends, you either top up at full price or spend the evening hunting for Wi-Fi. Some "unlimited" plans, like Holafly's, also describe usage conditions and tethering limits in their terms — read them before you buy.
VoaSim's approach is different: no data cap, no speed throttling, no hidden fair-use clause. One payment, one number to budget. See how the models stack up on our comparison pages.
Two travelers? Take another 10% off the second eSIM
Add a second eSIM to the same order and it gets an extra 10% off. For a couple doing 10 days in Athens plus Naxos, that is two independent unlimited lines instead of one phone tethering the other all day — which matters, because hotspot is not something we promise. It depends on the plan, so confirm with support before you rely on it.
Each person keeps their own maps, their own Instagram and their own battery. If you split up for a morning, nobody goes offline. Build the order for both travelers in the simulator and the discount appears at checkout.
Payment is by international credit or debit card in USD through Stripe. No hidden fees, invoice by email, no local-currency billing.
Today's prices
Today's promo prices (15% off), the same for every destination. Second eSIM in the same order: 10% extra off. Trips of 1-4 days use the 5-day package.
Coverage in Greece: Athens, the islands and the ferry gap
The eSIM connects automatically to Greek networks — Cosmote, Vodafone and Nova — picking whichever is strongest where you stand. You get 4G and, in many spots, 5G, though we never promise 5G because it depends on the local tower.
What works well:
- Athens — Acropolis area, Plaka, Monastiraki, the metro corridors and the airport link.
- Santorini and Mykonos — towns, ports and the main roads between them.
- Crete and Rhodes — Heraklion, Chania, Rhodes Town and the coastal resorts.
What to expect: on ferry crossings between islands the signal fades once you are in open water and comes back as you approach the next port. Download your tickets, maps and playlists before boarding. Same logic applies to cruises — a travel eSIM works on land at ports, not at sea. More on how our coverage works on the eSIM page.
Buying cheap without losing days: how validity counts
The classic way to waste money is to activate too early. Your VoaSim days start counting at the eSIM's first connection to a network at the destination, not at purchase and not at install.
- Buy and receive the QR code by email within minutes (plus a WhatsApp heads-up if you left a number).
- Install at home, on Wi-Fi, before you fly — installing does not start the clock.
- Keep the eSIM line switched off until you land in Athens or on your island. On Android, do not turn on the eSIM's data before the trip.
- On arrival, enable the eSIM line and turn off data roaming on your home carrier.
Your physical SIM and your phone number stay in the phone, so WhatsApp keeps working on your usual number. The eSIM is data only — no local phone number, no traditional voice calls, but app calls and maps run over data. Step-by-step install guides for iPhone and Android are in our guides.
Is your phone eligible — and what if it will not connect?
Cheap is worthless if the eSIM will not install. Dial *#06#: if an EID number appears, your phone supports eSIM. As a rule, that covers iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer and most phones released from 2020 on. Carrier-locked handsets must be unlocked first. VoaSim does not sell physical SIM cards.
If you land in Greece and see no signal, use the free eSIM Rescue tool — it diagnoses an eSIM of any brand, not just ours. Human support answers by chat or at hola@voasim.com, and if the eSIM will not connect and support cannot fix it, you get a 100% refund. More on how we handle that on the trust page.
When another option might beat a VoaSim eSIM
Fair is fair. If you are in Greece for two days, stay on hotel Wi-Fi and only need messaging, a small by-GB package from an app-based brand may cost less than USD 18.90. If you need a Greek phone number for SMS verification with a local service, a local physical SIM from Cosmote, Vodafone or Nova is the answer — expect a shop visit, passport registration and swapping out your own SIM.
Your home carrier's roaming (T-Mobile, AT&T, Verizon, EE, Vodafone, Three and others) can also make sense if your plan already bundles Europe. Rates and daily allowances change by plan and country, and speeds are often reduced after a daily allowance, so check the current terms in your carrier's app before you fly. Our roaming guide walks through the math.
If you are island-hopping for a week or more and live on maps and video, unlimited at a fixed price is usually the calmer choice.
Why trust VoaSim?
Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.
