Best ISP in Greece for 2026

Top ISPs in Greece at a glance

ISP breakdown

1. Cosmote/OTE

Cosmote is the mobile brand and OTE (Hellenic Telecommunications Organisation) is the fixed-line incumbent — both are part of the same Deutsche Telekom-owned group and together form Greece's dominant telecom. OTE operates Greece's national copper and growing fiber network. Its VDSL2 network has long been the dominant fixed broadband technology, delivering up to 100 Mbps in urban areas. Since 2022, OTE/Cosmote has accelerated FTTH deployment, now offering gigabit fiber in Athens, Thessaloniki, and an expanding list of Greek cities. OTE's geographic reach is unmatched — it is the only operator with significant coverage in rural areas and Greek islands.

2. Vodafone Greece

Vodafone Greece is the country's second-largest mobile operator and a growing fixed broadband provider. It operates both HFC cable and FTTH fiber infrastructure, concentrated in Athens, Thessaloniki, and major urban centers. Vodafone's cable network delivers strong download speeds, and its FTTH rollout is expanding. Vodafone competes effectively on bundled pricing — its combined mobile and home broadband packages offer genuine value for existing Vodafone mobile customers. Network performance in Athens is generally strong and competitive with OTE on equivalent plan tiers.

3. Nova (Wind Hellas)

Nova (formerly Wind Hellas, now rebranded) is a major telecom offering both mobile and fixed broadband. Nova operates cable and fiber infrastructure in major Greek cities and has been investing in its network since the merger with Forthnet's cable operations. Nova's cable network is well-established in the greater Athens area. Its pay TV service (Nova Sports and entertainment channels) is a draw for households wanting sports broadcasting alongside broadband. Fiber rollout is ongoing in urban areas.

4. Cyta Hellas

Cyta Hellas is the Greek subsidiary of Cyprus Telecommunications Authority (Cyta) and operates a fiber broadband network primarily in the Attica region (greater Athens). It is a smaller player than OTE, Vodafone, or Nova, but has carved out a niche offering competitive fiber pricing in the areas it covers. Plans go up to 500 Mbps. Cyta Hellas is a good option for users in Attica who want an alternative to the main operators.

5. Forthnet

Forthnet was historically one of Greece's main DSL and cable operators. Following corporate restructuring and partial acquisition by Nova, the Forthnet brand has been phased out in some product lines. Legacy Forthnet DSL customers are in the process of migration to other providers. Where Forthnet fiber has been deployed, speeds are competitive, but coverage is limited. New customers in Greece are better served looking at OTE, Vodafone, or Nova for their broadband needs.

How to choose the best ISP in Greece

1. OTE for coverage outside Athens and Thessaloniki — in regional Greece, islands, and rural areas, OTE is typically the only fixed broadband provider with meaningful coverage. Its VDSL network reaches addresses that no cable or fiber operator serves.
2. Vodafone or Nova for best speeds in Athens — in the greater Athens area, both Vodafone cable/fiber and Nova cable deliver strong speeds that can rival or exceed OTE VDSL. Check if FTTH is available at your address from any of the three.
3. Check island availability separately — Greek islands have very different connectivity landscapes. Major tourist islands like Crete, Rhodes, and Corfu have OTE VDSL coverage; smaller islands may have only mobile broadband or satellite options.
4. Nova for sports TV bundle — if you want Greek Super League and Champions League coverage alongside broadband, Nova's sports TV bundle is the primary option in Greece.

Internet speeds in Greece

Greece's median fixed broadband speed in early 2026 is approximately 80–100 Mbps according to Ookla Speedtest data — below the Western European average but improving rapidly as fiber deployment accelerates. Athens and Thessaloniki record median speeds of 120–180 Mbps in well-connected neighborhoods. Legacy VDSL connections, which still make up a large portion of Greek broadband, typically deliver 30–80 Mbps depending on line length and cabinet distance. Greece has received EU funding under the Digital Decade framework to support fiber rollout in underserved areas, and the national broadband plan targets gigabit-capable coverage for all urban areas by 2027.

Frequently Asked Questions

Is fiber broadband available on Greek islands?

Fiber availability on Greek islands varies significantly by island size and tourism profile. Major islands like Crete, Rhodes, Corfu, Kos, and Mykonos have OTE VDSL coverage and some FTTH deployment in their main towns. Smaller and more remote islands typically rely on OTE VDSL or ADSL, with mobile broadband (4G/5G) increasingly filling the gap for residents and tourists. Satellite broadband via Starlink is available across Greece including all islands and provides a consistent alternative where wired broadband is slow or unavailable. EU-funded broadband projects are bringing fiber to additional island communities progressively.

How does OTE/Cosmote broadband perform compared to EU averages?

OTE's VDSL network typically delivers 30–80 Mbps in practice — below the EU median of approximately 100 Mbps for fixed broadband. However, OTE's FTTH fiber service, available in a growing number of urban addresses, delivers 300 Mbps to 1 Gbps and is fully competitive with EU standards. Greece's overall fixed broadband median sits below the EU average primarily because of the high proportion of legacy VDSL connections still in use. As OTE's fiber rollout progresses and more households migrate from VDSL to FTTH, Greece's national average speed is expected to rise toward and then exceed the EU median within the next 2–3 years.
