eSIM for Greece: The Complete 2026 Travel Guide

Greece is the trip where your phone earns its keep: ferry timetables that change with the wind, a taverna at the end of an unmarked lane, the Acropolis ticket you booked for a time slot, and a hundred photos you want to send home before the sunset is over. An eSIM for Greece means all of that works from the moment the wheels touch down in Athens, Thessaloniki, Heraklion or Rhodes — and it costs a fraction of what roaming would.

Does an eSIM work in Greece?

Yes, and well. Greece has three national networks — COSMOTE, Vodafone Greece and NOVA — and a Greece eSIM from AirPlans connects to them at up to 5G in the cities and on the main islands, with solid 4G/LTE almost everywhere tourists go. Athens, Thessaloniki, Crete, Santorini, Mykonos, Rhodes, Corfu, Paros and Naxos are all well covered. The only places you should expect weak signal are remote mountain villages and a few stretches of open sea between islands — which is true for any SIM, local ones included.

Your phone needs to support eSIM. Every iPhone from the XS/XR onward does, as do recent Samsung Galaxy S and Z, Google Pixel 3 and newer, and most flagship Android phones from the last few years. If you are not sure, check our eSIM compatibility list before you buy — it takes ten seconds.

How much data do you need in Greece?

For most people the honest answer is 1 GB per day. Maps, WhatsApp, Instagram, a bit of browsing and the odd video call fit comfortably into that. Where it goes up is hotel Wi-Fi: on the islands it is often slow or shared with the whole building, so people end up using their eSIM for everything, including streaming in the evening. A rough guide:

• Weekend in Athens (3 days): 3 GB is plenty. You will be on café and museum Wi-Fi half the time.
• A week of island hopping: 5–10 GB. Ferries, beaches and ports are where you rely on mobile data, and photos add up.
• Two weeks or more, or working remotely: look at a 20 GB plan or an unlimited one. Unlimited plans on Greece come with a generous daily high-speed allowance, then slow down rather than cut off — good for video calls from a balcony in Paros.

Which Greece eSIM plan should you pick?

AirPlans currently lists close to fifty Greece plans, from 1 day to a full year, starting from around $3. The live prices are on the Greece eSIM page — they update in real time, and the number you see there is the number you pay at checkout. Three things to check before you choose:

• Validity starts when you activate, not when you buy. Buy it a week before the trip, install it at home, and it only starts counting down once you connect in Greece.
• Top-up. Most Greece plans can be topped up from your account without installing anything new, so it is fine to start with a smaller plan and add data if the island life stretches out.
• Going beyond Greece? If the trip continues to Italy, Turkey or the Balkans, a regional Europe eSIM covers all of it on one plan and saves you buying twice.

Set it up before you fly

The whole thing takes about two minutes, and you should do it at home on Wi-Fi rather than at the arrivals gate:

• Buy the plan. The QR code arrives by email straight away and also sits in your AirPlans account under My eSIMs.
• Scan the QR code from the phone's settings (iPhone: Settings → Cellular → Add eSIM; Android: Settings → Network & Internet → SIMs → Add eSIM). Give the new line a name you will recognise, like "Greece".
• Leave the new line switched off until you land, so the validity does not start early.
• When you land: switch the Greece line on, set it as your Mobile Data line, and turn Data Roaming on for that line only. Keep your home SIM active for calls and SMS, but make sure its own data roaming is off — that is the one that costs money.

Local tips that make the data go further

• Ferries: download your tickets and the Ferryhopper app before boarding. Signal on the open sea comes and goes; the ports themselves are fine.
• Athens metro: coverage underground is good on most lines, so navigation works on the way to the airport.
• Beaches and coves: the pretty ones are often in a cove with a cliff behind — that cliff also blocks the signal. Load the map before you climb down.
• Taxis: Uber in Athens books local taxis; on the islands, ask your hotel for a number and save it while you have signal.
• Hotspot: Greece plans on AirPlans allow tethering, so one eSIM can feed a laptop or a travel companion's phone in a pinch.

Do you lose your own number?

No. The eSIM is a second line that lives alongside your regular SIM. Your number, WhatsApp account and everything tied to it stay exactly as they are — the eSIM only carries the data. We wrote a short explainer on keeping your own number with a travel eSIM if you want the details.
