Choosing the best mobile network in Greece in 2026 depends much more on where you are going than on which carrier wins one speed test. I’m Greek and travel around the country regularly, so I compare Telekom (formerly Cosmote), Vodafone and Nova across the places where visitors actually notice a difference: islands, ferries, mountain roads, remote beaches, villages and cities. Independent 2026 measurements broadly support what I see on the road—but they also explain why Vodafone can look excellent in one metric while Telekom remains the network I would choose for a mixed Greece itinerary.
Updated 19 September 2026: includes the September Telekom rebrand, current Opensignal measurements and current Orange Travel Greece network access.
Telekom vs Vodafone vs Nova: Which Greece Network Is Best?
Telekom, formerly Cosmote, is still my overall choice for travelers who move around Greece. Vodafone is extremely competitive in cities and established resort areas, while Nova is perfectly usable for many simpler itineraries and should no longer be dismissed as a poor network.
My strongest all-around choice: ferries, islands, road trips, mountain areas, rural routes and itineraries that combine several parts of Greece.
My pick for mixed itineraries, ferries, islands and difficult terrain.
Excellent in cities, larger towns and major resort areas; particularly strong reliability metrics.
Solid in cities and popular destinations, but less convincing for remote terrain.
Cosmote is now officially Telekom in Greece. Deutsche Telekom announced the final brand transition in September; COSMOTE shops become Telekom shops and the mobile network name shown on phones changes to TELEKOM.GR. Older reports and eSIM listings still say Cosmote because they predate the change. Official Telekom announcement.
Telekom vs Vodafone vs Nova: Quick Comparison
The easiest way to choose is by matching the network to the trip rather than trying to name one winner for every situation.
| Trip style | What I would prioritize | Why |
|---|---|---|
| Mixed Greece itinerary | Telekom | Best all-around fit when the trip combines cities, islands, ferries and rural areas. |
| Islands, ferries & road trips | Telekom | My most dependable choice for difficult terrain, smaller islands and recovery after weak-signal stretches. |
| Athens, Thessaloniki & major resorts | Vodafone or Telekom | Both are strong enough that the practical difference can be small for a city-heavy trip. |
| Budget-focused city trip | Nova | Perfectly usable everyday performance without needing maximum nationwide coverage. |
| I do not want to choose one network | Multi-network travel eSIM | Orange Travel currently lists access to all three Greek networks. |
How I Compare Greek Mobile Networks
I compare Telekom, Vodafone and Nova by how their underlying networks behave while I travel around Greece—not by the logo on an eSIM marketplace. That means paying attention to the places where geography exposes real differences.
I do not expect every phone on every road to reproduce my exact experience. Device radios, buildings, terrain, congestion and roaming arrangements all matter. What I am looking for is the pattern that remains useful when planning a real itinerary.
What the Latest 2026 Mobile Data Actually Says
Opensignal’s March 2026 Greece report broadly supports my travel experience. Its data was collected before the final September rebrand, so the report calls Telekom by its old name, Cosmote.
| Opensignal metric | Telekom / Cosmote | Vodafone | Nova | Leader |
|---|---|---|---|---|
| Coverage Experience | 8.4 | 7.6 | 6.6 | Telekom |
| 5G Coverage Experience | 5.5 | 3.9 | 3.2 | Telekom |
| Download Speed Experience | 71.9 Mbps | 51.6 Mbps | 45.6 Mbps | Telekom |
| Upload Speed Experience | 12.6 Mbps | 10.6 Mbps | 9.5 Mbps | Telekom |
| Consistent Quality | 77.3% | 74.8% | 73.2% | Telekom |
| Reliability Experience | 873 | 902 | 889 | Vodafone |
| Time on Network | 96.8% | 98.3% | 96.1% | Vodafone |
| 5G Availability | 85.9% | 91.0% | 88.3% | Vodafone |
| Time on 5G | 29.1% | 20.6% | 17.6% | Telekom |
| 5G Download Speed | 185.6 Mbps | 152.9 Mbps | 145.4 Mbps | Telekom |
These metrics measure different things. Opensignal’s Coverage Experience is geographical and looks at the places people live, work and travel. Time on Network measures how much time users have a connection in the places they actually spend their time.
If the trip stays in Athens, Thessaloniki and major resorts, Vodafone’s reliability strengths are highly relevant. If the itinerary includes islands, mountain roads and rural routes, the broader coverage pattern is why I still lean Telekom.

Telekom (Formerly Cosmote)
Telekom is not perfect and it does not win every metric. What it does lead are several of the measurements I care about most for a varied Greece itinerary: Coverage Experience, 5G Coverage Experience, download speed and Consistent Quality.
That lines up closely with what I notice on island roads, ferry approaches, mountain routes and rural drives. When the trip goes well beyond major cities and resorts, Telekom is the network I am most comfortable prioritizing.
There is also a fresh naming wrinkle. Since September 2026, the consumer brand is simply Telekom. Older maps, reports and eSIM provider pages may still say Cosmote or COSMOTE TELEKOM; they are referring to the same underlying Greek network.
Vodafone Greece
Vodafone performs extremely well in the places where many visitors spend most of their time: Athens, Thessaloniki, Heraklion, Chania, Rhodes Town, Kos Town, Corfu Town and established resort areas. In these easier coverage environments, the practical difference from Telekom can be small.
Independent data confirms that Vodafone is not simply a distant second. In Opensignal’s 2026 measurements it leads Reliability Experience, Time on Network and 5G Availability.
The distinction becomes more useful once the terrain gets harder. In my travels I have found Telekom more convincing on some mountain roads, inland villages, remote beaches and ferry approaches. So I would happily use Vodafone for a city- or resort-heavy trip, but I still give Telekom the all-around edge for a route that wanders.
Nova Greece
Nova, formerly Wind, is often dismissed online using impressions that are increasingly outdated. In Athens, Thessaloniki, Patras, Heraklion, Chania and other large towns, it is fast and stable enough for ordinary travel use.
I also have a useful long-term reference point close to home: my mother uses Nova as her main mobile contract and travels around Greece regularly rather than remaining in one city. She is very happy with it. That obviously does not prove Nova matches Telekom everywhere, but it is a good reminder that “Nova is bad” is far too simplistic.
Where I become more cautious is harder geography: smaller islands, mountain roads, remote beaches and ferry approaches. For an easy city or major-island itinerary Nova can be absolutely fine; for a trip built around remote exploration I would choose Telekom first.
Best Greece Mobile Network for Ferries
Ferries are one of the clearest places where I notice differences. In my own ferry use, Telekom/Cosmote has generally reconnected first as the ship approaches land, Vodafone usually follows, and Nova has more often needed us to get closer to the port before the connection becomes properly usable.
No Greek terrestrial mobile network provides continuous coverage across open sea. Once the ferry gets far enough from land, losing normal mobile service is expected rather than evidence that the network is bad.
Best Greece Mobile Network for Islands
The islands are where the differences become most useful. In my experience, Telekom has been the most dependable across smaller villages, mountain roads, remote beaches and difficult terrain. Vodafone performs strongly in towns and established resort areas, while Nova works perfectly well on many popular islands but becomes less predictable as the route gets more remote.
For an island-heavy itinerary that goes beyond the port towns and resorts, Telekom remains my first choice.
Which Greece Network Should You Choose?
I would happily use Telekom or Vodafone. See my Athens eSIM guide or Thessaloniki eSIM guide for plan-level choices.
I would prioritize Telekom access, or use a multi-network travel eSIM that can switch between Greek carriers.
I would lean Telekom. My mainland Greece eSIM guide covers the harder rural use case.
Nova can be perfectly adequate and may be behind some lower-cost eSIM plans. You do not automatically need the “best” nationwide network.
A Practical Multi-Network Option
For a traveler, the commercial decision is often not “which Greek contract should I buy?” but “which travel eSIM gives me the network access I want?” That is why Orange Travel is unusually relevant to this page.
Orange Travel Greece eSIM
Orange currently lists Cosmote/Telekom, Vodafone and Nova as partner networks for its Greece eSIM and says the service can automatically select the strongest available network.
That makes it particularly attractive for a route mixing Athens, ferries, islands and mainland roads, where the strongest signal may change from place to place.

My Recommendation: Telekom vs Vodafone vs Nova
If you only remember one thing from this guide, make it this: Telekom is the Greek mobile network I would choose for the widest range of traveler itineraries. Vodafone is much closer than a simplistic first-versus-second ranking suggests and is excellent for cities and resorts. Nova is perfectly usable for many normal trips and deserves a better reputation than it still has online.
But if I were buying connectivity for a varied Greece trip rather than choosing a Greek mobile contract, I would not ignore the multi-network option. A plan that can access all three carriers can be more useful than committing to one “winner” before you know exactly where the weak spots on your route will be.

Frequently Asked Questions About Mobile Networks in Greece
What is the best mobile network in Greece in 2026?
Telekom, formerly Cosmote, is my overall choice for travelers because it combines the strongest nationwide coverage pattern with leading 2026 Opensignal scores for Coverage Experience, Consistent Quality and download speed. Vodafone is particularly competitive in cities and reliability metrics, while Nova is perfectly usable for many everyday trips.
Is Cosmote now Telekom in Greece?
Yes. COSMOTE TELEKOM became Telekom in September 2026. Shops, apps and mobile branding are transitioning to the Telekom name, and the network name displayed on phones becomes TELEKOM.GR. Older reports and eSIM listings may still say Cosmote.
Is Telekom better than Vodafone in Greece?
For a varied itinerary, I give Telekom the edge because its coverage strengths matter more once you leave major cities and resorts. Vodafone is extremely competitive for urban and resort travel and actually leads Opensignal’s Reliability Experience, Time on Network and 5G Availability metrics.
Why does Vodafone lead reliability if Telekom has better coverage?
The metrics measure different things. Coverage Experience is geographical and considers the places where users live, work and travel. Time on Network measures the proportion of time users have a connection in the places they actually spend their time. A network can therefore perform extremely well in everyday populated environments without having the broadest geographical reach.
Which mobile network is best for the Greek islands?
Telekom is my first choice for island-heavy trips because I have found it more dependable once the route moves away from port towns and resorts into smaller villages, mountain roads and remote beaches. Vodafone can be excellent in larger towns and established resorts, while Nova works well for easier island itineraries.
Which Greece network works best on ferries?
In my own ferry use, Telekom has generally reconnected first as the ship approaches land, with Vodafone usually following and Nova often becoming more reliable closer to port. No terrestrial Greek network provides continuous coverage across open sea.
Is Nova good enough for Greece?
Yes. Nova is perfectly usable for many Greece trips, particularly in cities, larger towns, major islands and established tourist areas. I still prefer Telekom for remote or terrain-heavy itineraries, but Nova’s old reputation for universally poor coverage is outdated.
Which Greece eSIM uses Telekom or Cosmote?
The answer depends on the provider and specific plan. Orange Travel currently lists access to Cosmote/Telekom, Vodafone and Nova for Greece, while other travel eSIMs may use only one or two Greek networks. See my Greece eSIM guide for the full provider comparison.
Can one Greece eSIM use all three networks?
Yes. Orange Travel currently lists Cosmote, Nova and Vodafone as its partner networks in Greece and says its eSIM automatically selects the strongest available network. That makes it especially interesting for varied itineraries, although roaming performance is not guaranteed to be identical to using a native local SIM.
