Install the eSIM before you leave. Land in Greece already connected.
Greece is in the European Union — but many roaming plans have hidden FUPs or daily charges that add up fast. With a BLIVALE Greece eSIM: 2-minute installation from home, truly unlimited data on Vodafone Greece and Cosmote, minimum 10 Mbps guaranteed, hotspot included — for the full duration of the plan. Works in Athens, the Cyclades, Crete, Rhodes and beyond.
1. The mobile network in Greece: Cosmote, Vodafone and Wind Hellas
Greece has three main operators — Cosmote (OTE Group, part of Deutsche Telekom), Vodafone Greece and Wind Hellas (now Nova). The BLIVALE Greece eSIM works on Vodafone Greece, Cosmote and Wind Hellas, ensuring maximum possible coverage on both the mainland and the islands.
✓ Used by BLIVALE
Cosmote
99%+ population coverage
The most extensive network in Greece. Undisputed leader on smaller islands, rural areas and ferry routes. 5G Standalone active.
✓ Used by BLIVALE
Vodafone Greece
~80% 5G coverage (45+ cities)
Excellent in urban areas and major tourist destinations (Santorini, Mykonos, Crete, Rhodes). €1 billion in 5G investment planned by 2029.
✓ Used by BLIVALE
Wind Hellas (Nova)
Solid in major cities
Good coverage in Athens, Thessaloniki, Patras and the main islands. Less present on smaller islands and remote rural areas.
Real-world speeds in Greece 2026: according to the latest Speedtest data, average 5G download speeds reach 350 Mbps on Cosmote, 200 Mbps on Vodafone and 150 Mbps on Nova. On 4G LTE, typical speeds are 40–80 Mbps — more than enough for streaming, video calls and remote work. BLIVALE guarantees a minimum of 10 Mbps for the entire duration of the plan.
2. Cost comparison: roaming vs eSIM in Greece
Greece is in the EU — but beware: the "free" roaming plans of non-EU operators (UK, USA, Australia) do not cover Greece or impose strict FUPs. Even from Italy, EU roaming plans often have speed or data limits. Here is a real-world comparison for 7 days.
| Option | Estimated cost 7 days | Data included | Notes |
|---|
Non-EU roaming (UK, USA, Australia) Day pass or pay-as-you-go |
€42–84+ |
Limited or FUP |
For travellers from UK, USA or Australia: Greece is not covered by free roaming. EE (UK) charges £7/day, AT&T $12/day. |
EU roaming with hidden FUP Italian, German, Finnish operators |
Included in plan* |
Domestic plan data (FUP) |
*FUP applied: speed reduced to 64–256 kbps after the threshold. Not truly unlimited. |
Greek local SIM Cosmote, Vodafone — airport or store |
€8–20 |
Limited data (10–50 GB) |
Requires queuing at the airport, often in English or Greek. Physical SIM swap. FUP after the threshold. |
BLIVALE eSIM Greece Unlimited ★ recommended |
from €23.70 |
Truly unlimited, no FUP |
QR code by email. 2-min installation from home. Connected on landing. Hotspot included. |
Watch out for FUP in EU roaming plans: even European travellers with "roaming included" in their domestic plan must check the FUP threshold. With most Italian, German and Finnish operators, after a few GB speed drops to 64–256 kbps — unusable for maps or video calls. The BLIVALE Greece eSIM has no FUP thresholds.
3. Why the eSIM beats a local SIM in Greece
No queues in Athens or Heraklion
Greek airports have SIM sales points — but with 20–40-minute queues at summer peak hours. You buy the eSIM from home, install it in 2 minutes, and when you land you are already online. No hunting for a Germanos or a Vodafone store in a foreign country.
Works on the islands with no reconfiguration
The BLIVALE Greece eSIM works automatically on both the mainland and the islands — Santorini, Mykonos, Crete, Rhodes, Corfu, Naxos, Paros. No additional setup when you board the ferry. The network automatically latches onto the operator with the strongest available signal.
Your home number stays active
The phone uses both SIMs simultaneously — the physical SIM for calls and SMS (including banking OTPs), the BLIVALE eSIM for data. Remember to disable data roaming on your home SIM before landing.
4. Greece eSIM plans: 7, 15 and 30 days
All Greece Unlimited plans include hotspot, a guaranteed minimum speed of 10 Mbps and no FUP. Validity starts from the moment of installation.

6. Coverage: Athens, islands and ferries
The Greek network is excellent in the main cities and the most visited islands. Here is what to expect at the most popular destinations.
🏛️
Athens
Excellent 4G/5G coverage across the entire city including the metro. The Acropolis and tourist areas are well covered. Cosmote and Vodafone offer 5G in the city centre.
5G / 4G LTE — excellent coverage
🌋
Santorini
Fira, Oia and the main beaches have good coverage. Watch out on the caldera cliffs: rocky terrain can cause drop-outs. In August the network is congested due to tourist volumes.
4G LTE — good in main areas
🎉
Mykonos
Mykonos Town (Chora), the port and the main beaches (Paradise, Super Paradise) are well covered. More remote beaches in the north of the island may have weak signal.
4G LTE — good in main areas
🏖️
Crete
Heraklion, Chania, Rethymnon: excellent coverage. North coast: outstanding. The Samaria Gorge (16 km) has no coverage. Remote beaches like Elafonisi: Cosmote works, Vodafone weaker.
4G LTE — strong on the north coast
⚔️
Rhodes
Rhodes Old Town, Lindos and Faliraki: excellent coverage. Smaller Dodecanese islands (Symi, Kalymnos) have more variable coverage, especially away from ports.
4G LTE — excellent in main areas
⛴️
Inter-island ferries
Near ports: good signal. In open sea between islands (e.g. Naxos–Paros): signal can be intermittent or absent. Download offline maps before boarding.
Variable — strong near ports
7. Practical tips for your trip to Greece
Essential apps for Greece
BEAT (FreeNow) — Athens' taxi app, works like Uber and is the safest option for taxis in the city. Ferryhopper — for booking ferries between the islands in real time. Google Maps offline — download the maps of the islands you plan to visit on the hotel Wi-Fi before taking the ferry.
Managing network congestion in peak season
In July and August, Santorini, Mykonos and the most popular islands fill with tourists — and the mobile network can become congested at peak hours. BLIVALE's guaranteed minimum speed of 10 Mbps ensures that even in these situations you have a usable connection for essential functions.
Hotspot for remote working from Greece
Hotspot is included at no extra cost on all Greece Unlimited plans. Perfect for anyone working remotely from a Greek island — connect your laptop and tablet and work on the same truly unlimited connection.
Island-hopping tip: if your itinerary covers multiple islands, the 15- or 30-day plan is the most convenient choice — a single eSIM works across all of Greece with no reconfiguration. You do not need a different SIM for each island.
