Simscanner measures every travel eSIM sold for Greece against the three host carriers a visitor can actually attach to: market leader Cosmote, long-established Vodafone Greece, and the value-driven challenger Nova. We weigh mainland and island coverage, real-world speed, reliability, unlimited terms and fair use clarity, never paid placement.
HelloRoam is Simscanner's top-ranked travel eSIM for Greece, with the cheapest sourced entry we tracked from $2.21. Greece registers prepaid SIMs by law, so loading an eSIM before you fly avoids the in-store passport check. Scan the ranking below.
Modelled estimates. Winner appears after verification.
Where a brand lands depends on its Greek coverage, its measured speed, how steady the connection holds, which of the three national carriers it leans on, whether its unlimited and FUP wording is honest, and what travellers report after a trip. We set the order ourselves and nobody pays to climb it.

Three licensed operators run under EETT oversight: Cosmote, the former state incumbent now owned through OTE by Deutsche Telekom, which leads the market and carries the widest network; Vodafone Greece, present since 1992; and Nova, the price-focused third player that grew out of the old Wind Hellas business and now sits inside United Group. Greece's geography makes carrier choice unusually important: a brand has to reach not just Athens and Thessaloniki but hundreds of inhabited islands across the Aegean and Ionian seas, where signal can thin out fast. A travel eSIM is a reseller, not a network, so whichever of the three it roams onto is what governs your bars in central Athens, in the hills of Crete, or on a ferry between Santorini and Mykonos.

Yes. Greece registers every prepaid SIM by law, so the seller must record a valid passport or national ID before the line will work. The shop or kiosk typically photographs or copies your photo identification, ties the Greek +30 number to your name and document number, and only then activates the SIM; you must also be at least 18. The rule is not new: Greece introduced mandatory identification of mobile-telephony owners and users in 2009 under Law 3783/2009 and announced it would block unregistered cards after July 2010. Law 3917/2011 then layered on a twelve-month data-retention duty, transposing the EU Data Retention Directive (2006/24/EC). Buy a travel eSIM from an international brand and load it before you arrive, and you generally sidestep that counter check, though the brand may run its own identity step at sign-up.
Greece sits at the south-eastern corner of the continent, sharing land borders with Albania, North Macedonia and Bulgaria to the north and Turkey to the east, with Italy a short hop across the Ionian Sea. What sets it apart from most of those neighbours is its EU and Eurozone membership: Greece joined the bloc in 1981 and uses the Euro, so a Greek or EU-issued plan rides the "roam like at home" rules and works without surcharge across members such as Italy, Bulgaria and Cyprus. Cross north into Albania or North Macedonia, or east into Turkey, and you leave that zone, so fees that disappear inside Greece can reappear. The deciding factor at each frontier is simply which roaming bucket your eSIM files the crossing under, not the strength of the bars. Greece also differs from a compact mainland country like Bulgaria in shape: coverage here is judged as much on the islands as on the cities, which is why an eSIM that performs well in Athens may still feel different on a smaller Cycladic island. We leave the fine print for each neighbour to its own Simscanner page rather than guess it here.
A line for every Greek plan, covering data, validity, price, carrier, hotspot rule and top-up. Brands rewrite these offers all the time and publish them live, so copying or estimating the figures is off the table. Each row stays blank until we have read it back against that brand's own Greece page.

"Unlimited" on a Greek plan almost never means without limits. A fair use policy usually lurks underneath, easing your speed down once a daily or whole-trip threshold is crossed. After we verify each plan, the grid records that threshold, the speed you fall to, and whether tethering survives.

The things people heading to Greece ask us most, answered without fuss. The full wording lives in the page so search engines and AI assistants can take in every line.
For a prepaid SIM, yes. Greek law has required registration since 2009, so a shop must record your passport or national ID, and you must be 18 or over, before the +30 line works. A travel eSIM bought from an international brand and loaded before you fly is handled through that brand's own sign-up, so you normally never reach the Greek counter check. See the ID and SIM registration section.
Under EETT there are three Greek carriers to roam on: market leader Cosmote, Vodafone Greece, and the price-focused Nova. A travel eSIM borrows one or more of them, and we confirm which one each brand actually uses, brand by brand, in the local networks table rather than assuming it.
It comes down to which of the three carriers your eSIM rides. All blanket Athens and Thessaloniki with 4G and 5G, but coverage on the smaller Aegean and Ionian islands depends on the host network, where Cosmote's wider footprint often helps. We have not yet published a verified Greek coverage ranking; each brand's coverage score lands in the ranking table once the data is checked.
Usually, if the plan is EU-issued. A Greek or EU eSIM travels under "roam like at home", so it works surcharge-free across members such as Italy, Bulgaria and Cyprus. The catch is the non-EU fringe: Albania, North Macedonia and Turkey sit outside the zone and can add fees. Confirm the covered countries on each brand in the region context section.
An eSIM goes live before you even leave the plane and avoids the passport-registration step a Greek prepaid SIM legally demands at the counter. A kiosk SIM at Athens might bundle a bigger local allowance, but you pay for it with that ID step and the queue behind it. Short hop or long stay tips the decision. See the ID and SIM registration section.
FUP, or fair use policy, is the point at which a brand is allowed to slow an "unlimited" plan. Our unlimited and FUP table breaks down the high-speed allowance, the speed you drop to once it runs out, and how clearly each brand spells this out, once the Greece figures are verified.
Every claim on this page about Greece's operators, its registration rule and its country basics appears below with the day we looked it up. Whatever we could not source, the plan prices, data amounts, validity, FUP terms, speeds and per-brand carrier links, is marked pending instead of guessed.
