Are you planning a holiday in Greece and want to know how to keep in touch with family, friends or local services? No problem, making calls to and from Greece is easy by knowing the correct dialling codes!

The international telephone code for Greece is 30 and should always be used to call Greek numbers from home. For example, to contact a Greek number, you would dial the international dialling code 00, followed by 30 and finally the Greek telephone number.

How to manage internet surfing after arriving in Greece? With an EU phone subscription, thanks to European roaming regulations, you can use mobile data in EU countries at no extra cost, with the same conditions as your plan. However, it is advisable to check with your operator the limits of data traffic available abroad, as there are often specific restrictions.

To limit data consumption, take advantage of the free Wi-Fi networks, which are readily available at cafés, accommodation facilities and public areas throughout Greece.

Call tariffs

If your phone plan is active in an EU country, you won’t have any surprises: in Greece your usual rates will apply thanks to the European roaming regulation. However, you may have to activate the roaming service by contacting your operator in advance.

For telephone contracts made outside the European Union, please note that each call will incur additional costs over and above the standard rate, depending on the operator. To keep your costs down, consider purchasing a Greek rechargeable SIM with packet minutes for your calls and data, or purchase an eSIM if your smartphone supports it.

eSIM

If the gigabytes available for surfing abroad are insufficient, consider purchasing an eSIM. This digital SIM allows you to add a second number without the need for a physical card, making it particularly advantageous for travellers wishing to reduce roaming costs. Here is the essential information:

How to activate an eSIM for your trip to Greece

  1. Check the compatibility of your device
    First of all, make sure that your smartphone supports eSIM technology. Recent devices such as the iPhone, Samsung Galaxy, Google Pixel and many other modern models offer this compatibility.
  2. Buy an eSIM from a local or international operator
    You can buy an eSIM from Greek operators or international providers specialising in solutions for travellers. Popular platforms for purchasing eSIMs include:
    Holafly: Ideal for travellers, with unlimited data offers in Europe.
    Airalo: Offers flexible plans from packages of a few GB for short stays.
    Cosmote or WIND: Main Greek operators that market eSIMs at official points of sale or via their respective websites.
  3. Download eSIM profile
    After purchase, you will receive a QR code or instructions by email. Simply scan the code with your phone to configure the profile and activate the data plan.
  4. Select eSIM as primary or secondary line
    You can choose to use the eSIM for data connection while keeping your physical SIM for calls. It is an effective solution to stay connected while keeping your regular number.

Local calls in Greece: When you are already on Greek territory, to call a local number simply dial the number normally, without international dialling codes.

Use messaging apps: To avoid high charges, especially for international calls, take advantage of apps such as WhatsApp. In addition to normal calls, they allow video calls with friends and family!

Check roaming conditions: Before departure, check with your operator whether your plan includes roaming calls and data for Greece. Many European plans include them at no extra cost, but it is best to check to avoid unpleasant surprises.

Take advantage of Wi-Fi connections: Greece offers many bars, restaurants and hotels with free Wi-Fi. Use it to surf online and make internet calls!

Consider a local SIM: The main operators in Greece are Cosmote, WIND and Vodafone. You can easily buy a prepaid SIM card at airports or in city shops.

Connectivity on islands: On the more remote Greek islands, network coverage may be limited. Check the situation in advance if you plan to visit smaller or less touristy islands.
