Cheapest eSIM for Greece (June 2026): 7 Providers Compared From $2.98

What is a Greece eSIM?

A Greece eSIM is a digital SIM you load onto your phone for mobile data while you travel, with no plastic card to swap.

You purchase your eSIM online, scan a QR code, and it joins a Greek carrier when you land at Athens or one of the island airports. Because you buy the eSIM online before you fly, there is none of the queueing or paperwork that comes with buying a SIM card at the airport. Your home SIM stays put, so you keep your usual number for the calls and bank codes that matter.

The plans on this page are travel data eSIMs, sold as fixed data packages or as unlimited durations.

Greece is firmly in the EU roaming zone, so an international eSIM bought for Greece usually keeps working across the wider EU at no extra cost, handy if your trip stitches together Greece, Italy and the Balkans. A travel eSIM is the simplest way to stay online for ferry bookings, maps and WhatsApp without a roaming bill or a queue at an airport kiosk.

Most short trips run fine on 1GB to 3GB, a typical week needs 5GB to 10GB, and heavy use calls for unlimited. Tell us how long you’re going and how you use your phone, and we’ll point you to the smallest plan that won’t run out, so you pay the least.

A rough guide based on typical use with offline maps and some free wifi. If you stream a lot or tether a laptop, lean to unlimited.

Which Greece eSIM is right for your trip?

For most visitors the cheapest pick is eSIM4: $5.98 for 2GB or $7.98 for 3GB on a short city break, and its unlimited plans for heavy island use or a longer stay. The exceptions are a fixed 10GB or 20GB (Nomad), a one-off 1GB teaser (Jetpac) and a 5- to 10-day unlimited trip (Nomad). Here is the quick read for each kind of traveller.

A few days in Athens

For a long weekend around the Acropolis and Plaka with maps and the odd photo upload, eSIM4 is cheapest at 2GB ($5.98) and 3GB ($7.98). If you only need a single gigabyte for a flying visit, Jetpac’s $1.00 1GB eSIM plan is the floor, though four days is the whole window.

A week on the islands

Island-hoppers tend to land on 5GB to 10GB once ferry apps, maps and messaging add up. eSIM4’s 5GB is $10.98, the cheapest at that size. At 10GB, Nomad ($16.00) slips under eSIM4 ($18.98), so a fixed 10GB plan is cheaper there.

Ferries and remote coves

This is where the carrier matters more than the price. Signal that is flawless in Athens or Heraklion thins out on open water between islands and in the small villages above the coast. If your route runs through the quieter Cyclades or a mountain road on Crete, favour a plan on the widest network and download offline maps before you leave the harbour town.

Heavy data or a long stay

For streaming on the ferry, tethering a laptop from a Santorini balcony, or two weeks plus across several islands, an unlimited plan saves the topping-up. eSIM4 has the cheapest unlimited at 3, 15 and 30 days, including a 30-day at $70.98 that no rival matches. For a 5- to 10-day unlimited stretch, Nomad is a touch cheaper.

One specific size, lowest price

If you want the floor on a single plan, Jetpac (1GB at $1.00) and Nomad (10GB at $16.00, 20GB at $20.00) own those tiers. For everything else, eSIM4 is the better value.

How much data do you need in Greece?

Plan on 1GB to 3GB for light use, 5GB to 10GB for a typical week, and unlimited if you stream or tether. Greek trips lean on data more than people expect once you add ferry-booking apps, Google Maps for villages with no signposting, restaurant lookups and a steady stream of photos from the caldera.

Industry figures put the average travel-eSIM user under 1GB a day, but island-hopping with heavy app use climbs past that. Map your likely data usage to the right size before you buy, since the cheapest data plan is the one that matches how you actually travel rather than the lowest sticker price. Treat this as a rough guide.

Light use: 1GB to 3GB

Maps, WhatsApp and a few uploads for a long weekend in Athens or one island. Fine for a short city break or a single-island stop.

A typical week: 5GB to 10GB

Daily navigation between sights, ferry apps, social media, a few video calls and some streaming over a week. This is the usual pick for an island-hopping week, and the band eSIM4 prices best, so it is usually the best deal at 5GB for a week of mixed use.

Heavy use or long stays: unlimited

Streaming on a long ferry crossing, tethering a laptop from a rental, or two weeks plus across several islands. An unlimited plan saves topping up at sea, and it is where eSIM4 is cheapest at the short and long durations. If you chew through a lot of data every day, a metered plan with plenty of GB of data can work out cheaper than an unlimited plan once the daily cap kicks in.

Greece mobile networks and coverage

Greece runs on three networks: Cosmote, Vodafone Greece and Nova. Cosmote has the widest reach, especially across the smaller islands and the mainland mountains, which is why it tends to be the safe default for anyone leaving Athens.

Vodafone Greece is strong too, particularly in the cities and the busier resorts. Nova is the smallest of the three. Most travel eSIMs do not run their own Greek network; they ride Cosmote or Vodafone wholesale, so the brand on your app matters less than which host carrier sits behind it.

Visitors report the same pattern again and again: an eSIM that is quick in Athens, Thessaloniki or central Heraklion drops to a bar or two on a ferry between islands, in the back lanes of a Cycladic village, or on a winding road in the Cretan interior.

The mainland cities and the main island towns are well covered. The gaps are the open-water crossings, the remote coves and the high villages. A plan riding Cosmote will usually hold on longer in those spots than one on a thinner host.

eSIM4 connects to a major Greek network with 4G LTE and 5G, the same infrastructure the premium brands resell, so the lower price does not cost you coverage. For a route through the quieter islands, download offline Google Maps for the whole region while you still have signal in the port.

Why some cheap eSIMs feel slow or block apps

Coverage is one thing, routing is another. Some very cheap eSIMs push your traffic through a server in another country to trim wholesale costs. When that happens you can see higher lag, slower loads and the occasional app that refuses to open or shows the wrong region, because services place you somewhere you are not. Greek banking apps, a couple of streaming libraries and even some ferry-operator sites are the usual casualties.

If a particular app matters on your trip, your bank or a ferry booking service, check the eSIM gives you a genuine Greek connection rather than routing the long way round. eSIM4 keeps your data on a major Greek network, so apps behave the way they do at home.

Is unlimited data really unlimited?

Yes for normal use, with one catch worth grasping before you pay for a Greek ‘unlimited’ plan. Almost every unlimited travel eSIM runs a fair-usage policy: full speed up to a daily high-speed allowance, then a slowdown for the rest of the day before it resets overnight. Travellers regularly report ‘unlimited’ plans easing off after 2GB to 5GB a day, sometimes to a crawl, which the marketing tends to skip over.

For maps, ferry apps, WhatsApp and social media you will rarely brush the cap. If you intend to stream in HD on every crossing or tether a laptop for work, read the daily allowance first, or take a large metered plan instead of trusting the word ‘unlimited’. eSIM4’s unlimited plans are listed by duration above, with the fair-usage terms shown at checkout.

eSIM vs airport SIM, roaming and local SIM

A travel eSIM is usually the cheapest and easiest way to get online in Greece, and the gap with a local prepaid SIM has all but vanished.

You purchase your eSIM and its data packages online before you fly, there is no deposit and no ID check, and it works the moment you land. An international eSIM that covers Greece also gives you flexible data options, from a single gigabyte to unlimited, without locking you into one bundle. The trade-offs are worth a look.

• Airport or kiosk prepaid SIM. Stalls at Athens airport and the island ports rarely have the best rates, and a carrier-shop prepaid wants ID and time you would rather spend on the beach. You also swap out your home SIM, losing your number while it is out.
• Carrier roaming. Easy but dear if you are outside the EU roam-like-home rules, often far above what a travel eSIM costs per GB.
• Local Greek prepaid with a number. A Cosmote or Vodafone prepay SIM gives you a real Greek number, useful for calling a hotel or a ferry desk, but buying a SIM card like this costs more than a data eSIM and needs activating in person.

For most visitors a data eSIM wins on price and convenience. If you are an EU resident, your own plan may already roam like home in Greece at no extra cost, so check that before buying anything.

Will your phone work with an eSIM in Greece

You need an eSIM-compatible, carrier-unlocked phone. Most handsets from the last few years qualify, including iPhone XS and newer, Pixel 3 and newer, and recent Samsung Galaxy S and Note models. Greek networks use standard European LTE and 5G bands, so band support is rarely the headache it can be elsewhere, but an unlocked phone is still the non-negotiable part.

On an iPhone dial *#06# to confirm an EID number, or check Settings for an ‘Add eSIM’ option. If your phone came on a carrier contract it may still be locked, so confirm it is unlocked before you rely on a third-party eSIM; Apple covers the steps in its carrier unlock guide and Pixel owners can check Google’s eSIM guide. Your home SIM stays in place, so you keep your number while the eSIM handles data.

How to set up your Greece eSIM

Set it up before you fly, then switch it on after you land. The whole job takes a few minutes over home wifi, and doing it early pays off in Greece because airport and port wifi can be patchy and slow right when you most want a signal.

1. Order your plan and the QR code arrives by email within a few minutes.
2. While you are still on home wifi, open Settings, then Cellular or Mobile Data, and tap Add eSIM. Apple’s eSIM setup guide covers every iPhone if your menus look different.
3. Scan the code and let the profile install at home. Leave it in place rather than deleting it to ‘tidy up’, since most codes work only once and a reissue means a support ticket.
4. Label the line something like ‘Greece data’ so you can tell it apart from your home SIM at a glance.
5. When you land in Greece, set the eSIM as your data line and turn data roaming on for that line only.

If your Greece eSIM will not connect

Most Greek connection hiccups sort themselves out quickly. Try these one at a time until the bars return.

1. Give it a few minutes after landing. On the tarmac and in the jet bridge the signal is thin, and the eSIM usually latches onto a network once you reach the arrivals hall.
2. Confirm the eSIM is your data line and that data roaming is switched on for it. Travel eSIMs need roaming enabled, since you are on a Greek carrier rather than your home one.
3. Switch airplane mode on for fifteen seconds, then off, so the phone hunts for a network again.
4. If it still will not connect, turn off automatic network selection and pick a Greek carrier by hand under Settings, then Mobile or Cellular, then Network selection. On a quiet island or a ferry, try Cosmote first since it tends to reach furthest.
5. On a crowded ferry where 5G keeps dropping, force the line to 4G for a more stable hold.

Travelling with one phone and nothing else to scan the code from? Save the QR as a photo before you leave home. On an iPhone you can long-press the saved image to add the eSIM, and on Android you can scan it from your gallery with Google Lens.

How we compared

We took each provider’s cheapest plan at every data size and duration and lined them up side by side, seven providers across every tier. Prices are in USD and were collected on 12 June 2026 from each provider’s own Greece page, then benchmarked against the rest of the market.

We exclude eSIMply, which mirrors eSIM4’s pricing and is not an independent provider, and we skip free-trial tiers since they are not a real paid plan. Coverage notes reflect the Greek host carrier each plan rides, Cosmote or Vodafone in most cases, and widely reported traveller experience, not a marketing claim. We re-check prices monthly and update this guide when they change.
