Prices are live and may change. Google Fi is excluded from the value ranking because it is a full phone plan rather than a travel data plan.
Cosmote, Vodafone Greece and Wind Hellas all run 5G across central Athens, Piraeus and the Attica coast. Cosmote leads on 5G availability and indoor coverage in older neighbourhoods.
The Athens-Thessaloniki corridor and the main tourist routes through central Greece have 4G everywhere, with 5G in the bigger towns. Mountain roads to the Meteora monasteries and through the Pindus see brief drops.
Main villages on each island and the major beaches are well covered. Remote inland chapels and quieter beaches on Naxos and Paros lean on Cosmote for usable signal.
Heraklion, Chania and Rethymno have 5G; the north-coast tourist corridor stays connected. The Lasithi Plateau, Samaria Gorge interior and the southern coast around Sfakia get patchy on every carrier.
Rhodes, Kos, Skiathos, Corfu and Zakynthos all hold strong 4G in their main towns. Smaller islands like Symi, Patmos and Kefalonia's western beaches frequently see only Cosmote with reliable signal.
Athens
- Arriving
- Eleftherios Venizelos (ATH) is the main hub - the Metro Line 3 (Blue) connects directly to Syntagma Square in 40 minutes with continuous cellular signal at depth. The Suburban Railway (Proastiakos) is the slower alternative. All terminals have full 5G from Cosmote, Vodafone Greece and Wind Hellas (now Nova). The X95 Express Bus to Syntagma runs 24/7.
- On the subway and rail
- Athens Metro (3 lines: Red 2, Green 1, Blue 3) has cellular coverage on every underground station and tunnel - all three carriers run 4G/5G at depth, including the deep Syntagma and Monastiraki interchanges. The Athens Tram (Lines T1, T6 along the coast to Piraeus and Glyfada) keeps signal throughout. OASA buses and trolleybuses are continuously covered. The Suburban Railway and the OSE Intercity to Thessaloniki stay live.
- Free public WiFi
- Athens WiFi is the city-deployed network covering Syntagma Square, Monastiraki, the National Garden, Thissio and the Plaka tourist district - SMS-based one-time registration. The Acropolis and Acropolis Museum visitor areas have free WiFi. ATH airport gives 1 hour free with extensions via TripAdvisor partnership. Cafes universally have open WiFi (Mikel, everest, Coffee Island).
- Coverage in the city
- Cosmote (OTE Group, the incumbent) has the densest 5G across Athens - particularly strong indoor coverage in the older Plaka and Monastiraki tavernas where ancient walls can block signal. Vodafone Greece is highly competitive in Kolonaki, the Athenian Riviera (Glyfada, Vouliagmeni) and the new Stavros Niarchos Foundation Cultural Center area. Nova (formerly Wind Hellas) is solid through the centre. Coverage at the Acropolis Hill, Lycabettus Hill funicular and the Panathenaic Stadium is excellent on all carriers. The Piraeus port terminals for Aegean ferries stay connected.
- If you prefer a local SIM
- Cosmote, Vodafone Greece and Nova all have stores at ATH arrivals and throughout central Athens (Ermou Street, Stadiou). EU regional eSIM plans are usually the easiest path. Tourist prepaid SIMs from €15 with several GBs over 30 days. AB Vassilopoulos and Sklavenitis supermarkets stock prepaid SIMs. ID required.
Santorini
- Arriving
- Santorini National Airport (JTR) is small - mostly seasonal European charter flights and Aegean/Olympic domestic. No rail. KTEL Santorini bus from the airport to Fira (the capital) takes 20-30 minutes; signal holds throughout. Most travellers transfer to Oia or one of the cliffside villages via taxi or pre-arranged transfer. The Athinios Port is where ferries from Athens (Piraeus) and the other Cyclades arrive.
- On the subway and rail
- Santorini has no metro - everything is buses, taxis, ATVs and cliffside pathways. KTEL Santorini buses connect Fira to Oia, Imerovigli, Akrotiri (the red beach), Kamari and Perissa (black sand beaches), Pyrgos and Megalochori. All buses maintain cellular signal. The cable car from Fira to the Old Port stays connected; the donkey path and walking trail also have signal but are exhausting. The Fira-Oia coastal hike (about 3 hours) has signal throughout with a few brief drops at the deeper cliff sections.
- Free public WiFi
- Santorini hotels, especially the cliffside infinity-pool boutique hotels in Oia and Imerovigli, universally have guest WiFi - it's a selling point. Cafes throughout Fira and Oia have open WiFi. The Akrotiri archaeological site has limited public WiFi at the visitor centre. JTR airport gives 1 hour free. Public WiFi in Fira's main square and Oia's sunset viewpoint is available with email registration.
- Coverage in the city
- Cosmote, Vodafone Greece and Nova all have 4G coverage across Santorini with 5G appearing in Fira and Oia. Cosmote is the most consistent on the western caldera cliff villages (Oia, Imerovigli, Firostefani, Fira). Vodafone is strong on the eastern beach side (Kamari, Perissa, Perivolos). Nova covers the basics. Coverage on the famous Oia sunset point, the Fira-to-Oia hike and the Akrotiri Minoan ruins is solid. The Anhydrous (red beach) and the Caldera ferry tours stay connected close to shore.
- If you prefer a local SIM
- Cosmote and Vodafone have stores in Fira town centre - tourist plans similar to Athens. For a 3-5 day Santorini visit, an EU regional eSIM plan or Cosmote tourist prepaid is the standard. Bring passport. The Cosmote shop in Fira is the most reliable for English-speaking activation help.
Grab an eSIM before you arrive in Greece to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.
Greece offers strong mobile connectivity for travelers exploring its ancient ruins, stunning islands, and vibrant cities. Cosmote, Vodafone Greece, and Wind Hellas deliver 5G in Athens, Thessaloniki, and Patras, while reliable 4G covers most of the mainland and popular islands like Crete, Santorini, Mykonos, Rhodes, and Corfu.
The Greek islands are a major draw for tourists, and the larger, more visited islands maintain solid 4G coverage in towns and resort areas. Smaller, more remote islands and mountainous interior regions may have reduced coverage or rely on 3G. Ferry routes between islands can lose signal mid-crossing.
As an EU member, Greece is included in European regional eSIM plans, making it cost-effective to combine with other Mediterranean destinations. Data is particularly useful for navigating the winding streets of island towns and checking ferry schedules in real time.
- Popular islands like Santorini, Mykonos, and Crete have reliable 4G in towns and tourist areas
- Ferry crossings between islands may lose signal mid-journey - download entertainment beforehand
- EU regional eSIM plans cover Greece - ideal for combining with Turkey or other Mediterranean stops
- Download offline maps for remote islands and mountainous interior regions
- Data is essential for real-time ferry schedule updates via apps like Ferryhopper

- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the Greece eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Decide on your dual-SIM strategy.
Keep your home line on for SMS-based bank logins, two-factor codes, and emergency calls. Set the travel eSIM as the data line only. Most modern phones can do both simultaneously.
- 4
Disable iMessage on the travel eSIM line.
Otherwise iMessage will try to re-activate against the new line on arrival and you will spend the first ten minutes troubleshooting it instead of finding the taxi rank.
- 5
Download offline maps for Greece.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.
We are building this section from real, verified traveler submissions rather than stock testimonials, so it stays empty until we have notes we can stand behind. If you have used an eSIM in Greece recently, a one-paragraph note on what worked (and what did not) helps the next traveler.
