Athens Thessaloniki Patras Larissa Heraklion
Greece has solid 4G/LTE coverage across the mainland and all major tourist islands. Cosmote (Deutsche Telekom group) provides the widest national footprint and leads in 5G deployment in Athens and Thessaloniki. Vodafone Greece and Wind supplement coverage in Aegean island groups. All major islands — Santorini, Mykonos, Rhodes, Corfu, Zakynthos, Crete — have reliable 4G in resort towns and main roads. Smaller Aegean islands (Symi, Kastellorizo, Patmos) have coverage in ports and main villages; rural and clifftop areas may be 3G. Ferry routes between Athens (Piraeus) and major islands maintain connectivity in port and coastal areas. High-altitude areas on Crete's White Mountains and Samaria Gorge may have limited signal.
Plan size
How much data do you need?
Pick your travel style and trip length — we'll suggest the right Greece plan, no guessing.
Yes. Coverage in Crete, Santorini, Mykonos, Rhodes, Corfu, Zakynthos, and all major islands. Very small or remote Aegean islands may have limited coverage in rural areas.
How is coverage at remote beaches?
Beaches near populated areas and resorts have good 4G. Very remote beaches accessible only by boat or long hike may have weaker signals — this is typical for island destinations.
How does pricing compare to Airalo Greece?
Flysimio is priced below Airalo for the same plan at typical sizes. You get the same Cosmote/Vodafone network at a lower price.
Does this work on ferries between islands?
Coverage is available near ports and coastlines. Open sea crossings on longer routes (e.g., Athens to Heraklion) may drop to 3G or lose signal in the middle of the route.
What speeds can I expect?
4G/LTE with speeds up to 100 Mbps in major cities and resort areas. 5G available in Athens and Thessaloniki.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. We offer a full refund within 7 days of purchase. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
eSIM in Greece
The complete guide.
Best eSIM for travel to Greece
The best Greece eSIM combines strong island coverage, clear pricing, and instant setup. Flysimio runs on Cosmote, Vodafone, and Wind — networks that cover Athens and Thessaloniki plus the islands of Santorini, Mykonos, Crete, and Rhodes — with 5G in the major cities. Plans are prepaid with no contract and no roaming bill surprises: choose your data, pay once, done. Your QR code arrives by email seconds after checkout and installs in under a minute, every plan includes free mobile hotspot, and a 7-day money-back guarantee has you covered. Land at Athens or on a Greek island already connected and skip the kiosk entirely.
How to set up a Greece eSIM (step by step)
Getting online in Greece takes about two minutes. First, confirm your phone supports eSIM — iPhone XS (2018) and newer and most Android flagships from 2020 qualify. Choose your Greece plan on Flysimio and pay with card, Apple Pay, or Google Pay; your QR code arrives by email within seconds. On Wi-Fi before you fly, open Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android) and scan it — a manual code is included too. Keep your home line as default until arrival. When you land at Athens, Thessaloniki, or Heraklion, your Flysimio line connects automatically to a Greek network — no kiosk, no physical SIM, no queue.
How much data do you need in Greece?
Most travellers over-buy. For maps, messaging, and email, roughly 300 MB a day is plenty, so a 3–5 GB plan covers a week of island-hopping comfortably. Add social media, sunset photos, and music and you'll want about 700 MB a day — a 10 GB plan suits a two-week trip across Athens and the islands. Heavy streamers, video callers, and anyone tethering a laptop should plan for 1.5 GB or more per day or choose an unlimited daily plan. One note: long open-sea ferry crossings can lose signal mid-route, so download maps first. Use the calculator above to size it, and top up mid-trip if you run low.
Using a Greece eSIM on iPhone and Android
Flysimio runs as a second line beside your usual SIM, so you keep your home number for calls and texts while your Greek data flows over the eSIM — standard dual-SIM behaviour on iPhone XS and later and most Android phones from 2018. After installing, set the Flysimio eSIM as your cellular-data line and turn on Data Roaming for that line only; it simply lets the eSIM connect to Greek networks, with no roaming fees. Keep your home SIM on for messages and calls, or switch it off to avoid your own carrier's charges. If you're unsure about your model, the compatibility page confirms it before you buy.
Hotspot, calls, and texts on a Greece data eSIM
Every Flysimio Greece plan includes mobile hotspot at no extra cost and without throttling, so you can tether a laptop or tablet or share with a travel companion and use your full allowance freely. As a data-only eSIM it has no Greek phone number, but that rarely matters: WhatsApp, FaceTime, Messenger, and Google Meet handle calls and messages over data, and your home number stays reachable on your primary SIM. You stay connected from Athens to the Aegean without the per-minute charges of traditional roaming.
Short Greece trips vs. long stays
For a long weekend in Athens or a quick island escape, a small 1–5 GB plan on a 7-day validity is the most economical choice. For a two-week island-hop across the Cyclades or a longer stay, a 10–20 GB plan or an unlimited daily option lets you navigate, stream, and share without watching a meter. Because Flysimio gives you six months to activate, you can buy before you leave and the validity only starts when your eSIM first connects in Greece. No contract, nothing to cancel — the plan stops when it's done, and you can top up or rebuy for your next trip.
