How much does a Greece eSIM cost?
Plans run from 1 GB to unlimited data, for 3 to 30 days. Prices change, so check the live plans before you buy a Greece eSIM.
Which network does a Greece eSIM use?
The eSIM connects to a local network in Greece. You get 5G where it is available; elsewhere you are on 4G, which is fine for maps and messaging.
How much data do you actually need?
Navigation eats about 100 MB a day. Messaging and social media add another 150–200 MB. So a normal week of maps, WhatsApp and the occasional photo upload lands around 2–3 GB total. Video is the exception: an hour of streaming is roughly 1 GB. If you plan to video-call or stream on long transit legs, that changes the math.
When is unlimited data worth it?
Only when you know you’ll stream or tether. If you’re on maps and messaging, unlimited is money you won’t use. But if you’re working remotely and hotspotting a laptop every day, a larger or unlimited plan is cheaper than buying a small one and running out.
Dual-SIM: keep your bank OTPs
A data-only eSIM leaves your physical SIM slot free, so your home number keeps receiving bank verification texts at no extra cost. That’s the setup to use if your bank still sends one-time passwords by SMS.
Arrival and getting around
At Athens Airport, the Metro line 3 reaches the city centre in about 40 minutes. Around Athens the metro runs on a rechargeable card, and ferries from Piraeus link the islands. The eSIM is active the moment you land, so you can pull up transit directions before you clear passport control.
How to install and activate
- Scan the QR code from your order email under Settings → Cellular → Add eSIM.
- Label the plan so you can tell it apart from your home SIM.
- Turn on data roaming for the eSIM once you land. The plan starts counting from the first connection.
Will my phone work with it?
Any carrier-unlocked phone that supports eSIM will work: iPhone XS or newer, Pixel 3 or newer, and Samsung Galaxy S20 or newer are the common ones. If your phone is locked to a carrier, unlock it first or the install will fail at the QR step.
Frequently Asked Questions About Greece eSIMs
Q1: How much data do I need for a week in Greece?
About 2–3 GB for maps, messaging and the occasional photo upload. An hour of video streaming uses roughly 1 GB more.
Q2: Which network does the eSIM connect to?
The eSIM connects to a local network in Greece.
Q3: Can I use it as a hotspot?
Yes, hotspot and tethering are enabled on every plan. A laptop or a second phone can share the connection.
Q4: When does the plan start counting?
From the first connection to a local network after landing, not from the moment you scan the QR code. Install it at home on Wi-Fi and activate on arrival.
Q5: Does it work outside the big cities?
Yes. It works anywhere in Greece where the local network has signal, including the islands. Signal can be weaker in remote areas.
Q6: Can I top up or extend it?
Topping up depends on the plan. The simplest option is to buy a longer plan up front if your dates are fixed; check the live plan list for what’s available.
Q7: What if I run out of data?
Buy a second plan and install it the same way. The first one keeps working until its days or its data run out, whichever comes first.
Q8: Does it work with WhatsApp and FaceTime?
Yes. Calls and messages through WhatsApp, FaceTime, Zalo or Viber run over data, so you don’t need a local number.
Q9: Will I get 5G everywhere?
No. 5G is used where it is available. Elsewhere you are on 4G, which handles navigation and messaging without a problem.
Q10: What’s the refund policy?
You get a 100% refund if your phone does not support eSIM or is locked to a carrier, the eSIM has not been installed or activated, and you claim within 14 days of purchase. You also get a full refund if your eSIM is not delivered. If a technical error on our side stops the eSIM from activating, or the local network is down or the signal is too poor to use it, and our support team cannot fix it, we will refund it in full (for a technical error on our side, we may replace the eSIM instead). We do not give refunds for a change of mind, or once the eSIM has been installed or activated (except for a technical error or a local network problem). Full details: Cancellation & Refund Policy.
Bottom line
For a Greece trip, a single data-only eSIM is the least-fuss option, and 2–3 GB covers a normal week. Pick the size that matches your video habit, install it before you fly, and you’ll have signal the moment you land. Compare the live Greece eSIM plans.
