Choosing an eSIM for Greece or a local prepaid SIM can make it easier to use maps, book tickets, check transport and stay connected throughout your trip. For many visitors, an eSIM is the simplest option, while a physical Greece SIM card can still make sense if you need a local phone number.
This guide compares the main options for tourists, including Polo eSIM, Holafly, Airalo and Roamless, as well as prepaid SIM cards from Greek mobile operators.
Do You Need a SIM Card in Greece?
If your mobile plan is from an EU or EEA country, you can generally use calls, SMS and mobile data in Greece under the EU’s Roam Like at Home rules. Fair-use limits can apply, particularly to data allowances, so check your provider before travelling. (European Union)
Visitors from countries outside the EU/EEA should check their carrier’s international roaming charges. Depending on your plan, a Greece eSIM or prepaid local SIM may be a more economical option.

Which eSIM Should You Choose?
Buying a Physical SIM Card in Greece
If you prefer a Greece prepaid SIM, the country’s main mobile operators are:
- Cosmote
- Vodafone Greece
- Nova
Prepaid packages are available through operator stores and authorised retailers. Offers, data allowances and validity periods change regularly, so compare the current plans rather than relying on old package prices.
Vodafone, for example, currently offers prepaid options specifically for visitors to Greece and states that a valid passport or ID is required when ordering a new prepaid SIM.
A physical SIM card for Greece is particularly useful if having a local Greek number is important to you.
Where to Buy a SIM Card in Athens
The simplest option is to visit an official Cosmote, Vodafone or Nova store in Athens or an authorised retailer.
You can also buy a SIM card at Athens Airport. Athens International Airport currently lists Sim Local, which sells voice and data SIM cards from mobile operators. Its staffed locations include the Arrivals area and baggage-reclaim area.
If you are not in a hurry, buying your SIM after reaching central Athens also gives you more opportunity to compare available packages.
What Do You Need to Buy a SIM Card in Greece?
Physical prepaid mobile connections in Greece require identification when they are registered.
Visitors should therefore bring a valid passport or accepted official ID when purchasing a local prepaid SIM. Vodafone’s current tourist SIM information specifically confirms the use of a valid passport or ID. (vodafone.gr)
Requirements can vary slightly by operator or sales channel, so bring your passport even if you also carry a national identity card.
Travel eSIMs work differently because you are purchasing an international data service rather than registering a new Greek prepaid number with a local operator.
Mobile Coverage in Greece and the Islands
Greece has extensive 4G coverage, while 5G is available across many populated areas. Actual performance depends on your location and the Greek network used by your SIM or eSIM.
Coverage can become less consistent on remote islands, in mountainous areas or while travelling by ferry between islands.
For this reason, when comparing the best eSIM for Greece, it is worth checking not only the amount of data but also which local networks the selected plan can access.
