Greece – Landlines and Mobile Phones

What are the international dialling codes for Greece, and what are the area codes for the most popular expat destinations?

Greece’s international country code is +30. To reach a Greek number from overseas, you dial your international access prefix (typically 00 or +), then 30, followed by the complete local number. Greece transitioned to a closed ten-digit numbering scheme in 2001–2002, which means every digit — including the area code — must always be dialled in its entirety, even for calls within the same locality.

One detail worth understanding: unlike many countries where the leading zero of an area code is omitted when calling from abroad, Greece’s system operates differently. Area codes exist in two-, three-, and four-digit forms. The sole two-digit area code is 21, which belongs to the Athens Metropolitan area; three-digit codes apply to Thessaloniki, Patras, Larissa, Heraklion, Kavala, and Tripoli. All remaining area codes consist of four digits. Because all ten digits are always dialled in full, there is no leading zero to remove — the entire number string is used consistently whether you are calling from within Greece or from abroad.

A frequent source of confusion is the assumption that Athens’s area code is 210, when it is in fact 21 — the “0” belongs to the subscriber number rather than the area code. Because some subscriber numbers beginning with 0 were allocated to the former monopoly OTE, numbers starting with 210 and 211 both fall under the 21 area code, even though callers often mistake 211 for a separate area code.

The table below shows area code digits and dialling formats for locations frequently chosen by expats. To call from abroad, add +30 before the full ten-digit number:

All Greek mobile numbers begin with 69x, so a complete mobile number looks like: +30 69X XXX XXXX. For a comprehensive and up-to-date list of area codes, refer to the Hellenic Telecommunications and Post Commission (EETT), the national telecoms regulator.

Who are the major landline providers in Greece, and how can you contact them?

The Greek telecoms sector has been deregulated, and a range of companies now compete for customers. COSMOTE, which grew out of the former state monopoly, continues to hold the largest share of the fixed-line market. Since the market was opened up to competition, COSMOTE (OTE) has gradually ceded ground to rivals such as Vodafone and Nova.

All the leading telecoms companies in Greece now bundle landline, mobile, internet, and in some cases television services together. Signing up for a combined package typically attracts better pricing than taking individual services separately. Because tariffs and plan structures change regularly, you should always verify current offers on each provider’s official website before making a decision.

The principal fixed-line providers are:

• OTE / Cosmote — The incumbent operator and market leader for fixed lines. Customer Service: 134; Business customer services: 13 818; Emergencies (from OTE fixed line, free): 121; Emergencies (from mobile or other lines): 13 888. Website: www.cosmote.gr. Note: in April 2025, the OTE Group adopted “Cosmote Telekom” branding, aligning with Deutsche Telekom’s integrated service strategy.
• Vodafone Greece — Offers fixed-line services as part of bundled packages including mobile and broadband. Customer service from a Vodafone mobile: 1212. Website: www.vodafone.gr. Check the website for current tariffs (as of 2025).
• Nova (formerly Wind) — Nova Greece Telecom, formerly known as WIND, is a prominent Greek telecommunications company offering mobile, fixed-line telephone, internet access, and television services. Customer service from a Nova mobile: 1260. Website: www.nova.gr. Check the website for current tariffs (as of 2025).

Landline services are frequently bundled with internet access and may include digital television. Pricing varies across providers and depends on which package you select. Applications can generally be submitted via the provider’s website, by phone, or in person at a store or service centre. Always obtain up-to-date pricing directly from the provider before committing. Consumers can also raise complaints or seek guidance on their rights through the EETT (Hellenic Telecommunications and Post Commission).

Who are the major mobile phone providers in Greece, and how can you contact them?

The Greek mobile market is competitive, with three principal network operators and a number of MVNOs (Mobile Virtual Network Operators) also in operation. The three main companies are Cosmote, Vodafone, and Nova, each of which provides both prepaid and postpaid (contract) options.

• Cosmote — Cosmote is the largest Greek mobile operator with over 7 million subscribers. It uses the brands Cosmote and What’s Up for its mobile services, and provides 3G and 4G/LTE services with the best overall coverage in Greece. In June 2024, Cosmote commercially launched its 5G standalone access (SA) network, branding it as 5G+. Customer service from a Cosmote mobile: 133; from any other line: +30 210 618 0000. Website: www.cosmote.gr.
• Vodafone Greece — Vodafone Greece has about five million subscribers, making it the second-largest mobile operator in Greece. It provides 3G and 4G/LTE networks and also has a network-sharing agreement with Nova for better coverage. Customer service from a Vodafone mobile: 1212. Website: www.vodafone.gr.
• Nova (formerly Wind) — Nova has nearly 4.5 million customers and is in third place in the Greek market. It provides 3G and 4G/LTE networks. Though coverage is more limited than its rivals, it offers affordable pricing. Customer service from a Nova mobile: 1260; from other lines: +30 210 61 50000. Website: www.nova.gr.

Beyond the three network owners, several MVNOs lease capacity from the main operators: Forthnet operates on Wind/Nova’s network and sells prepaid plans with unlimited data; Cyta runs on Vodafone’s network for mobile and fixed broadband bundles; and Vectone Mobile uses Cosmote’s network to provide budget-focused prepaid plans.

Independent analysis published by Opensignal in January 2025 found that Cosmote leads the field, with 4G reaching 99% of populated areas; Vodafone puts in a strong showing with 97% 4G coverage and is particularly consistent in cities and tourist hotspots; while Nova achieves 94% 4G coverage and continues to extend its footprint in less densely populated regions.

Although Greece performs respectably in global rankings for mobile internet speeds, maintaining consistent quality — especially in rural regions — remains a challenge. On the islands and in mountainous terrain, signal reliability can vary; Cosmote is generally the most dependable choice when venturing to remote locations. Current plan pricing changes frequently, so check each provider’s official website for the latest information (as of 2025).

How do I get a landline connected in Greece?

Depending on which telecoms provider you select, arranging a new landline can be done in person at a local branch, by telephone, or online. The process broadly mirrors that of other European countries, though waiting times can stretch out — particularly away from Athens. Always confirm current requirements and estimated timescales directly with your chosen provider or with the EETT.

Most landlines are installed alongside a router and internet connection, and are typically not transferable between individuals — when someone moves out they either cancel the service or take it with them. If the infrastructure is already in place from a previous occupant, take time to review the existing package before agreeing to continue it, as you may well find a more cost-effective deal elsewhere — providers regularly introduce new offers and promotional pricing.

The typical steps involved in setting up a new landline are as follows:

1. Choose a provider. Review bundled offers from OTE/Cosmote, Vodafone, and Nova. Combining landline, mobile, and internet services in one package usually yields a better price than signing up separately.
2. Gather your documents. You will need a passport or national identity card, proof of address (such as a lease agreement or utility bill), and a contact number. A Greek residence permit is generally required, as is a Greek Tax Identification Number (AFM) for contract-based services.
3. Apply. Applications can normally be submitted online, by phone, or by visiting a store or service centre. To connect through OTE/Cosmote specifically, you can attend a local branch or call 134.
4. Sign the contract and pay any deposit. A contract is signed; a deposit may be requested. There is a waiting period for line installation; businesses and people with special needs may be given special consideration.
5. Wait for installation. Expect a wait of approximately two to four weeks, though delays are possible. OTE/Cosmote connections tend to be processed more quickly than those with other providers; OTE also allows new line orders to be placed online.
6. Technician visit. An installation appointment will be arranged and a technician will visit the property to carry out the physical connection work.
7. Transferring an existing line. Where an existing telephone line needs to be transferred from one account holder to another, both parties must attend an OTE store together; the outgoing account holder settles any outstanding balance and the contract is formally transferred to the new occupant.

Some providers may impose a minimum contract term or conduct a credit assessment before approving an application. Whether you own or rent the property generally makes little difference to the process, though landlord consent may be needed if significant physical work to the building’s infrastructure is required. Always verify exact documentation requirements directly with your chosen provider, as these are subject to change.

How do I get a mobile phone SIM card or contract in Greece?

Obtaining a mobile SIM in Greece is a straightforward process that can be completed on the day of your arrival. The steps differ somewhat depending on whether you choose a prepaid (pay-as-you-go) SIM or a postpaid monthly contract.

Prepaid SIMs

To purchase a SIM card in Greece you must present your passport for identification purposes. The provider will record or photograph your ID to register the SIM against your name and passport number. Only individuals aged 18 or over are permitted to purchase a SIM card in Greece. This aligns with the approach taken across most EU member states following EU-wide SIM registration regulations.

Prepaid SIMs are available through a number of channels:

• You can purchase a prepaid physical SIM card at Athens airport — either in the baggage claim area or within the arrivals hall — though prices there may be higher than in city-centre shops.
• In major cities and tourist areas like Thessaloniki and Patras, local shops and convenience stores sell prepaid SIM cards, though the range of options may be narrower than at operator stores.
• Greece’s network of kiosks (περίπτερα/periptera) operates around the clock and is found throughout the country — many stock prepaid SIMs and top-up vouchers.
• You can also buy directly from official network operator stores for the widest selection of plans.

Activation is typically immediate. Top-ups can be completed online or at the many retail outlets that display top-up signs.

Postpaid contracts

A Greek tax identification number (AFM) and proof of identity is usually required to get a mobile phone with a monthly contract. You will also typically need a Greek bank account and proof of address, such as a rental agreement or a utility bill. Newcomers who do not yet have residency documentation in place may find prepaid options more immediately accessible, since contracts generally require proof of lawful residence in Greece.

Unlike some countries — such as Australia, where postpaid arrangements can sometimes be established with only a passport — Greece’s contract process involves more documentation, which reflects standard EU telecoms practice. Once you have your AFM and a local address, taking out a contract is relatively simple and can often be done in-store or online.

Some operators may impose additional requirements on foreign nationals, such as evidence of where you are staying in Greece or documentation confirming your lawful presence in the country. Always check with the provider directly for the most current requirements, as these can evolve.

How do I pay my telephone bill in Greece?

Telecoms bills are issued monthly, and the majority of customers now opt to receive them electronically and settle them online through their provider’s website or via internet banking. This reflects the broader shift across Europe towards paperless billing and digital payment methods as the default approach.

Payments can also be made in person at provider stores or authorised agents, by bank transfer, or by setting up an automatic debit from your bank account. Many providers additionally support payment through their mobile app or by text message.

The main payment options available are:

• Direct debit (automatic bank debit): The most convenient choice for residents with a Greek bank account, with bills drawn automatically each month without any action required.
• Online banking or provider website: Settle your bill through your Greek bank’s digital platform or directly via the provider’s own app or website.
• In person at provider stores or authorised agents: Including certain bank branches and payment networks such as ELTA (Hellenic Post).
• Prepaid top-up: Pay-as-you-go mobile customers can top up their credit online or at any of the thousands of outlets displaying top-up signage.

Paying on time is important to avoid service interruptions or penalty charges. If you anticipate difficulty meeting a payment deadline, contact your provider promptly to discuss the options available to you. Late payment terms vary between operators, so review the conditions set out in your contract. For billing disputes or broader service complaints, the EETT (Hellenic Telecommunications and Post Commission) is the independent regulator responsible for consumer telecoms oversight.

Are there any practical tips for using phones in Greece as a newcomer?

EU roaming

A Greek SIM can roam freely throughout the EU, allowing you to use your plan’s included allowances while travelling in other member states. This is a meaningful benefit for expats who travel regularly within Europe. If you arrive with a non-EU SIM and intend to use it temporarily, check the applicable roaming rates carefully, as they can be considerable.

5G coverage

Greece is actively extending its 5G infrastructure. Athens already has solid 5G coverage, and the rollout is steadily reaching other regions, including rural areas and the islands. Cosmote leads outright in both general Coverage Experience and 5G Coverage Experience, meaning Cosmote subscribers enjoy the widest geographical coverage — including 5G — in populated areas.

Rural and island coverage

In remote island locations and mountainous areas, signal quality can be more variable, though in populated places it is perfectly adequate for everyday use. If you are moving to a rural area or a smaller island, it is advisable to consult individual operator coverage maps before signing a contract. Cosmote generally provides the most extensive reach in less-connected locations.

eSIMs

Most Greek operators support eSIM, but not universally: Cosmote launched eSIM in 2022; Vodafone currently offers eSIM with ongoing development; Nova does not yet have eSIM capability. International eSIM providers also sell Greece data plans before you travel, which is a practical way to avoid the immediate need for a physical SIM on arrival. If your handset supports eSIM, this can be a convenient option during your first few weeks while you decide on a long-term plan.

Number porting

Number portability can make it difficult to identify which carrier is responsible for a given number. Moving a Greek mobile number between operators is permitted and regulated. You will need your current account details and, in most cases, your AFM. Transferring a landline to a different provider typically takes around three weeks. Unlike some countries where mobile porting is completed within a single working day, the timeline in Greece can span several days — confirm the current expected duration with your new provider.

Keeping a foreign number

It is not possible to port a foreign number directly into the Greek telephone system. If staying reachable on a foreign number is important to you, the most workable approaches are to keep a separate home-country SIM active (roaming charges will apply), to use a VoIP service (such as a second number via WhatsApp or Google Voice), or to use a dual-SIM handset.

Local phone customs

WhatsApp and Viber are used extensively in Greece for both voice calls and messaging, and are often favoured over traditional SMS for everyday communication. Businesses, landlords, and local contacts will frequently expect to communicate via these apps. Having a Greek mobile number — even a prepaid one — from your earliest days in the country will make daily life considerably more straightforward.

For the most current regulatory information, consumer rights guidance, and complaint procedures relating to telecoms in Greece, consult the Hellenic Telecommunications and Post Commission (EETT).

Frequently asked questions

Can I keep my foreign number when I move to Greece?

It is not possible to port a foreign number into the Greek telephone network. That said, you can maintain a foreign SIM alongside a Greek one in a dual-SIM device, or use a VoIP application such as WhatsApp or Viber linked to your previous number to stay reachable for contacts overseas. Most expats find it easiest to acquire a Greek number promptly and let their contacts know about the change.

Do I need a local address to get a SIM card in Greece?

For a prepaid SIM, a passport or national ID card is the main requirement — a local address is not always mandatory, though some operators may request one. You may also be asked to provide the address at which you are staying in Greece or other documentation confirming your lawful presence in the country. For a postpaid contract, proof of a Greek address (such as a tenancy agreement) is generally expected alongside your AFM and identity documents.

Can I get a mobile contract in Greece without a Greek tax number (AFM)?

A tax identification number and proof of identity is usually required to get a mobile phone with a monthly contract. Without an AFM, you are likely to be restricted to prepaid options. Registering for an AFM is one of the very first administrative tasks recommended upon arriving in Greece, and it is needed for most formal agreements and services.

How long does it take to get a landline installed in Greece?

Installation typically takes between two and four weeks, though delays are possible. OTE/Cosmote connections tend to be processed more quickly than those arranged through other providers, and OTE also allows new line orders to be submitted online. Always confirm the current expected timeframe with your chosen provider, as lead times can differ by region.

Is 4G or 5G coverage reliable in the Greek islands?

Cosmote leads coverage with 99% of populated areas covered by 4G across the mainland and islands. On well-known tourist islands such as Santorini, Mykonos, Rhodes, and Crete, 4G service from all three operators is generally dependable in town centres and resort areas. More remote or smaller islands may experience patchy coverage — check your intended operator’s coverage map for your specific destination before selecting a plan.

Are eSIMs available in Greece?

Greek operators support eSIM to varying extents: Cosmote introduced eSIM in 2022; Vodafone currently offers it with further expansion under way; Nova does not yet provide eSIM capability. Third-party international eSIM providers also sell Greece data plans that connect via local networks, which can be a practical solution for newcomers before they have a local SIM organised. Verify eSIM availability directly with the operator, as the picture continues to evolve.

What are the emergency telephone numbers in Greece?

The principal emergency numbers in Greece are: 112 (the pan-EU emergency number, accessible from any phone including mobiles with no SIM inserted); 100 (Hellenic Police); 199 (Fire Brigade); 166 (National Emergency Medical Services / EKAB). The 112 number operates in multiple languages and is the most reliable option for foreign nationals facing an emergency.

How do I complain about a telephone provider in Greece?

If a dispute with a telecoms provider cannot be settled directly, you can escalate the matter to the Hellenic Telecommunications and Post Commission (EETT), the independent authority responsible for regulating consumer telecoms rights in Greece. Complaints can be lodged through their official website. The Consumer Ombudsman (Συνήγορος του Καταναλωτή) also handles consumer disputes and can be reached at www.synigoroskatanaloti.gr.
