Greece means islands, and that shapes the SIM card decision. Cosmote, the former state carrier, has the most extensive island coverage across the Aegean and Ionian seas. For anyone planning to hop between Santorini, Mykonos, Crete, Rhodes, and smaller islands like Milos or Paros, Cosmote is the practical choice. Vodafone Greece is strong on the mainland and popular tourist islands but thinner on the smaller Cyclades. Both carriers have counters at Athens International Airport in the arrivals hall. Plans roam across the EU. The typical tourist plan from Cosmote is 12 EUR for 10 GB over 10 days, including 200 minutes of local calls. Most carrier stores in tourist areas close for a midday break from about 2 PM to 5 PM, which catches visitors off guard.

Greece has three carriers: Cosmote (largest, best island coverage), Vodafone Greece, and Wind Hellas. Athens Airport (ATH) has Cosmote and Vodafone stores in arrivals. As an EU member, any EU SIM card roams in Greece at domestic rates. Cosmote covers more Greek islands than its competitors.

eSIM for Greece: the fastest option

Travel eSIMs skip the physical SIM process entirely. Buy online, scan a QR code, and your phone connects to a local network. No passport check, no airport queue, no SIM ejector tool. Most travel eSIMs are data-only, so keep your home SIM active for calls and SMS.

Local Cosmote SIM is easy to buy in Athens. eSIM is the top choice for island-hopping itineraries where buying a local SIM is less practical and EU roaming covers connections to other European destinations.

Coverage noteeSIM Greece uses Cosmote network. 4G LTE in Athens, Santorini, Mykonos, Crete, and Rhodes. Best Greek island and ferry port coverage.

Where to buy a SIM card in Greece

The best place to buy is Athens International Airport arrivals or Cosmote/Vodafone stores in tourist areas. Here is what each channel offers and what to expect.

Airport

Airport counters are the most convenient option on arrival day. Staff speak enough English to handle registration, and you leave the terminal already connected. Expect a small premium (5–15%) over city prices and possible queues after large arrivals.

Carrier Store

Official carrier stores carry every plan, can troubleshoot activation on the spot, and have English-speaking staff in tourist-heavy areas. Prices match the carrier website.

Online

Ordering online before you fly means you land already connected. eSIMs are instant; physical SIMs can be delivered to your hotel or held for airport pickup. Best prices overall.

Our verdictAthens International Airport arrivals or Cosmote/Vodafone stores in tourist areas

Buying experience

At Athens Eleftherios Venizelos Airport, the Cosmote and Vodafone counters are both in the arrivals hall past the baggage area. Registration requires your passport or EU ID. The process takes about 10 minutes. In Athens city, the Monastiraki and Syntagma area has multiple carrier stores. On the islands, look for carrier stores in the port towns: Fira on Santorini, Mykonos Town, and Heraklion on Crete all have Cosmote shops. On smaller islands like Naxos, Paros, and Ios, the carrier presence is limited to one or two shops open during tourist season hours. Top-up cards are available at kiosks (periptera) throughout Greece.

Local tipAt Athens Eleftherios Venizelos Airport, the Cosmote store is in the arrivals hall near the exit. A tourist SIM with 10 GB costs about 10-15 EUR. In Mykonos and Santorini, Cosmote shops in the main towns handle top-ups. For smaller islands, top up before you leave Athens or a major island.

Cosmote leads on overall coverage with a rating of 5/5 for reach and 5/5 for speed. In cities, all providers perform similarly. Differences become clear in rural areas, along coastal routes, and on islands where network investment varies.

Real-world connectivity

Athens has strong 4G from Cosmote and Vodafone across the city and the Metro system in most stations. Santorini and Mykonos have excellent coverage in the main towns. The caldera rim villages on Santorini all get signal. Crete: Heraklion, Chania, and Rethymno are well covered. The Samaria Gorge hike has Cosmote signal at the top in Omalos and at the bottom in Agia Roumeli but nothing in the gorge itself. Naxos has coverage in Hora. Rhodes city and the west coast resorts are fully covered. Remote northern Aegean islands like Samothrace and Limnos have Cosmote coverage in main towns only. Ferry crossings between islands will lose signal in the open Aegean.

Our verdict on SIM cards in Greece

Bottom lineGreece has strong mobile coverage on the mainland and major islands. Cosmote (OTE Group) leads in coverage, especially on smaller islands that Vodafone and Wind skip. For island-hopping, eSIM with EU roaming is the most practical option since you stay connected on every ferry and island without visiting carrier shops.

Best for: Island-hopping travelers, Athens and Santorini visitors, Multi-country Mediterranean travelers.

Watch outSmall Cycladic islands (Folegandros, Anafi, Koufonisia) may have coverage from Cosmote only. Ferry signal drops mid-crossing between islands. Mountainous areas of Crete's interior (Samaria Gorge) have limited signal. EU roaming means any EU SIM works in Greece without extra cost.

Local Cosmote SIMs cost about 10-15 EUR for 10 GB. eSIM with EU roaming costs a similar amount and works across all 27 EU countries. For island-hopping or multi-country Mediterranean trips, eSIM is clearly more practical than buying a local SIM at each stop.

Activation & registration

Passport requiredGreece requires SIM registration with a valid passport. Have it ready at the point of sale. The process takes 5–15 minutes depending on the vendor.
  1. Check your phone is unlocked

    Your device must be carrier-unlocked to accept a Greece SIM. Check Settings or contact your home carrier before you leave.

  2. Choose a plan before you buy

    Decide on data volume and validity period. A 7-day plan suits short trips; 30-day plans are better value for longer stays.

  3. Bring your passport

    Registration is mandatory. The vendor scans your passport ID page and enters details into a government portal. Keep your passport accessible.

  4. Insert and configure

    Insert the nano-SIM using the ejector tool. Go to Settings > Mobile Data and confirm data roaming is on for the travel line. Run a speed test to confirm you are connected.

Tips for travelers in Greece

  1. Cosmote has the best coverage on Greek islands. If you plan to island-hop, Cosmote is the safest choice.

  2. Greek SIM cards roam free across the EU. Use the same SIM in Italy, Croatia, or any other EU country.

  3. Carrier stores may close for afternoon break (3-5 PM). Airport counters have longer hours.

  4. Coverage on popular islands (Santorini, Mykonos, Crete, Rhodes) is generally excellent with all carriers.

  5. Small, remote islands may have weaker signal. Download offline maps before visiting.

Common mistakes to avoid

Watch outThese are the most common errors travelers make when buying a SIM card in Greece. Each one can leave you without data when you need it most.
  1. Not buying a SIM before heading to the islands. Carrier stores on small islands can be hard to find.

  2. Assuming all island ferries have strong signal. Coverage can drop during open sea crossings.
