Best eSIM for Greece 2026: 7 providers compared

Part of our Greece eSIM guide: all articles and key facts →

If your SIM card comes from an EU country, you can skip this page: you already roam in Greece at home prices. Everyone else, from British, American, Canadian or Swiss travellers to visitors from Morocco, Latin America or the Gulf, pays their own operator's roaming rates, and a travel eSIM is usually the cheapest way to stay online from the Acropolis to the beaches of Crete.

We read the Greece pages of seven providers on 26 October 2026 and compared price, network, daily caps and coverage notes, for trips from a stopover in Athens to a month of island hopping. All prices are those displayed on the providers' own pages that day; dollar prices are converted at the European Central Bank rate of 23 October 2026 (1 euro for 1.1193 dollars) where we compare them with euro prices.

Which is the best eSIM for Greece?

For unlimited data, Ubigi was the cheapest Greece-only plan for a week, two weeks and a month, Yesim for one, three and ten days; for a fixed allowance, Ubigi and Orange Travel led. These verdicts cover single-country plans; Maya Mobile's global plan costs less again and is discussed below. Here are the winners by need, on prices checked on 26 October 2026:

• A stopover in Athens (1 day): Yesim sells 1 day of unlimited data for €3.50 and Holafly for €3.90.
• A long weekend (3 days): Yesim costs €10.50, Airalo €11 (3 GB a day at full speed, then 1 Mbps) and Holafly €11.42.
• Five days: Orange Travel's unlimited plan costs €16.99, a price its product data marks as valid until 15 November 2026; Yesim and Airalo cost €17.50.
• One week, Athens plus one island: Ubigi costs €22 (20 GB at full speed, then 2 Mbps), Yesim €24.50, Airalo €25 and Holafly €25.50.
• Ten days of island hopping: Yesim costs €29.94, Orange Travel €30.99 and Airalo €31.50; Nomad's $33 (about €29.48) slows to 1 Mbps after 2 GB a day.
• Two weeks: Ubigi costs €36 for 15 days with 30 GB at full speed, Orange Travel €37.99, Yesim €39, Airalo €44.50 and Holafly €47.90.
• A month: Ubigi costs €55 with 60 GB at full speed, Yesim €57, Airalo €63.50 and Holafly €70.90.
• A light user with hotel Wi-Fi: Ubigi sells 3 GB valid 30 days for €6 and 10 GB for €12; Yesim sells 1 GB for €2.50.

If your trip continues to Turkey, read our Turkey eSIM guide before you leave home: Greece-only plans stop at the border, and several eSIM sellers' websites are blocked from inside Turkey.

Do you need a travel eSIM in Greece?

Not if your SIM comes from the EU or the EEA; very probably yes if it comes from anywhere else. Under the EU's "roam like at home" rules, a SIM from an EU country, Iceland, Liechtenstein or Norway, and also from Moldova and Ukraine, works in Greece at domestic prices, as the EU’s Your Europe page explains. Your operator may still apply a fair-use limit, which for limited-data contracts "can be lower than your domestic data allowance". The page adds: "Other countries are not covered by this regime."

This guide is therefore for everyone else. Since Brexit, British operators set their own European prices. On 26 October 2026, Vodafone UK’s roaming page placed Greece in its Europe zone and sold a European Roaming Pass at £16 for 8 days or £21 for 15 days, subject to a 25 GB fair-use policy. In the US, AT&T’s International Day Pass cost $12 a day for the first line and Verizon’s TravelPass $12 a day, both valid in more than 210 destinations; check that Greece is on the list for your plan.

Compare those figures with a week of unlimited data at €22 to €25 on a travel eSIM, or with Vodafone Greece's tourist bundle described in our Greek SIM guide. A travel eSIM also leaves your home number active for calls and bank codes by SMS, as long as you control roaming on that line.

The Greece eSIMs side by side

The table lists the Greek networks each provider names, its unlimited week and a typical fixed plan, as read on the providers' pages on 26 October 2026 in the currency each page displayed.

Unlimited prices by length complete the picture. Holafly sells any number of days from 1 to 90 and Yesim any number from 1 to 30; Airalo sells 3, 5, 7, 10, 15 and 30 days; Ubigi 7, 15 and 30 days; Orange Travel 5 to 25 days.

Saily also sells Greece plans, but its site refused automated reading on 26 October 2026, so we leave it out of every verdict.

Is an unlimited eSIM for Greece worth it?

For a week or more with heavy use of maps, photos and video calls, yes; for a light user with hotel Wi-Fi, a fixed plan costs half as much. A week of unlimited data costs €22 to €25.50 at Ubigi, Yesim, Airalo and Holafly, against €12.99 for Orange Travel's 10 GB valid 7 days and €10 for Ubigi's.

The fine print is what separates the offers:

• Ubigi: "Your unlimited data plan includes 20GB of full speed data, then optimized to 2 Mbps" on the 7-day plan; 30 GB on the 15-day plan and 60 GB on the 30-day plan.
• Airalo: "Lower speed rate of 1 Mbps after 3 GB usage per day", stated on every unlimited plan.
• Nomad: "2GB/day at 4G/5G. 1 Mbps after 2GB".
• Maya Mobile: "5GB Per Day full speed, then speed drops to 3Mbps", although its headline promises "no caps, no throttling".
• Holafly: its FAQ says a fair usage policy may be applied for "no more than one (1) day", without a figure.
• Yesim and Orange Travel: Yesim says only that speed "may be limited" under the operator's fair usage policy; we found no speed rule for Orange Travel's unlimited plans.

Maya Mobile is the outlier. Its Greece page sells one global plan, valid in more than 165 countries, at $9.99 for 3 days, $19.99 for 7 days, $27.99 for 14 days and $49.99 for 30 days, or €8.49, €16.99, €23.79 and €42.49 in its own euro prices. Its FAQ says each package is a one-time purchase with "no automatic recurring charge unless you choose to turn on Auto Top-Up", while the page also says plans auto-renew "while Travel Mode is on": check that setting after you buy. With 5 GB a day at full speed, it is cheaper than every Greece-only unlimited plan at each length it sells.

Telekom, Vodafone or Nova: which network does each eSIM use?

Greece has three mobile networks: Telekom, known as Cosmote until September 2026, Vodafone and Nova, once called Wind. Most travel eSIMs connect to Nova and Vodafone; only two of the seven we compared name Telekom. Yesim names Cosmote, Vodafone and Wind, and Orange Travel names Cosmote, Nova and Vodafone; Airalo, Holafly, Nomad and Maya name Nova and Vodafone; Ubigi names Nova only. The old names on sellers' pages refer to the same networks: Cosmote completed its switch to the Telekom brand in September 2026.

That matters, because Telekom came out ahead in the latest independent measurements. Opensignal’s Greece report of September 2026 is built from measurements taken by its users between 1 April and 29 June 2026.

Telekom won download speed, coverage and consistent quality outright; Vodafone kept its users connected the highest share of time; Nova improved on almost every measure but finished third. Reliability was a three-way tie. For a traveller, the practical conclusion is that a plan able to use two networks, such as Airalo's, Nomad's or Holafly's, has a fallback when one signal drops, and a plan that includes Telekom, such as Yesim's or Orange Travel's, gives access to the network with the widest measured coverage.

On 5G, Airalo labels its Nova connection 5G and its Vodafone connection 4G, Nomad lists Vodafone in 5G, and Yesim lists 5G on Cosmote and Wind. Whether you actually get 5G also depends on your phone.

Will your eSIM work on Santorini, Mykonos, Crete and the ferries?

On the islands themselves, yes: travel eSIMs use the same land networks as Greek SIM cards. At sea and on small, thinly populated islands, expect gaps. Airalo’s Greece plan states that it "covers mainland Greece but also other Greek islands including Crete, Santorini, Mykonos, Rhodes, Corfu, Kos and more". Holafly’s Greece page is frank about the limits: "In mountainous regions, sparsely inhabited islands and during boat journeys, coverage may be more limited or unstable", citing parts of the Pindus mountains, Mount Olympus, the Samaria Gorge on Crete, and "some small islands or remote coastal areas".

We found no independent, island-by-island measurement we could read. Opensignal's national coverage score, which measures signal where its users live, work and travel, puts Telekom ahead (8.4 out of 10) of Vodafone (7.6) and Nova (6.7). If you plan hikes on Crete or stays on the smaller Cyclades, a plan that includes Telekom, or one that switches between two networks, is the safer choice.

Ferries deserve a word of caution. Near the coast, your phone stays on a Greek land network. Further out, it may lose signal or pick up a network on board the ship. The EU’s Your Europe page warns that when services on ships are provided "via satellite systems, EU rules no longer apply" and calls are billed as unregulated roaming, without price caps. That warning targets home SIMs: before boarding, switch off data roaming on your home line and leave only the travel eSIM line active for data. Download offline maps and ferry tickets before you sail.

On the airports used by island hoppers, see our Greek SIM guide, which explains where Vodafone sells tourist lines.

Is a Greek tourist SIM cheaper than a travel eSIM?

For a month, yes: Vodafone's tourist bundle undercuts every Greece-only unlimited eSIM, but you need to buy it in Greece with your passport. On 26 October 2026, Vodafone’s tourist page listed unlimited data in Greece plus 200 minutes to Greek numbers for 30 days at €27, and 25 GB plus 200 minutes for 20 days at €18.10. The page shows a top-up of €30 and €20 respectively to load those bundles, and an eSIM option at €9.90 in its online order. Nova's prepaid brands advertise far larger allowances, such as 250 GB for 30 days at €14.20 on FREE2GO, but they are built for residents and ordered with a Greek delivery address.

A Greek line also gives you a local number, useful for restaurants, taxis and ferry agencies. The catch is the paperwork and the timing: you register with a passport or ID, either online before delivery or at a shop or airport kiosk. Our guide to Greek SIM cards compares Telekom, Vodafone and Nova and explains where to buy. A travel eSIM, by contrast, is the only option you can fully arrange before departure.

What should you sort out before flying to Athens or the islands?

Buy and install the eSIM at home, check that your phone is unlocked, and decide what happens to your home line. The eSIM profile then switches on when you land at Athens, Thessaloniki, Heraklion or an island airport.

• eSIM support: find your model on our list of eSIM-compatible phones.
• Unlocked: a phone locked to your home operator will refuse a foreign profile. Read do you need an unlocked phone for a travel eSIM.
• Installation: on Android, follow our step-by-step eSIM activation guide; if the line stays on "Activating", see our fixes for an eSIM stuck on activating.
• Your home line: keep it on for SMS codes but switch off its data roaming, especially on ferries; our guide to running two eSIMs at the same time explains the settings, and our article on roaming charges to check before travelling lists the traps.
• Validity: Yesim, Holafly and Ubigi start the plan when the eSIM connects in Greece, Airalo on first use; Nomad asks you to activate within 60 days of purchase and Yesim within 180 days.

If a seller asks for your phone's EID, our guide shows where to find the EID number. If nothing connects on arrival, check that data roaming is on for the eSIM line and that it is selected for mobile data, then work through 10 fixes for a travel eSIM not working abroad.

How we compared

We read each provider's Greece page, or the plan data it embeds, on 26 October 2026, and recorded price, validity, data, networks, speed cap, start of validity and hotspot rule. Several sites served us a cached page for another country on a first request; every figure here comes from a page confirmed as the Greece page. Euro prices are those displayed; Nomad's dollar prices are converted at the European Central Bank rate of 23 October 2026, the latest published on the day we read the pages (1 euro for 1.1193 dollars), and Maya's euro prices are its own. Orange Travel's allowances and validities are taken from its product data.

Network figures come from Opensignal's September 2026 Greece report; roaming rules from the EU's Your Europe page; local offers from Vodafone Greece's and Nova's own pages. Telekom's prepaid pages blocked automated reading, so we give no Telekom prices. We did not buy the plans or test them in Greece. Prices change often, and several Orange Travel offers are marked valid until 15 November 2026, so check the provider's page before you buy.
