Greece eSIM
data from $2.59.

If you are looking for the best eSIM for Greece, buy a data only plan before you fly and land connected in Athens. Slashtel eSIM plans for Greece start from $2.59, run on Wind, Vodafone and Cosmote, and cover Athens plus the islands you hop between. There is no local number and no calls or texts, just mobile data on 5G where available.

Choosing an eSIM for Greece

What matters most is that your plan connects to the main Greek networks, gives you enough data for the trip, stays valid for your dates, supports hotspot and is installed before you leave.

Coverage is the first thing to check. A Greece eSIM should work across more than one network, because signal varies between Athens, the mainland and the islands. Slashtel plans connect to Wind, Vodafone and Cosmote, and your phone picks the network automatically as you move. You do not choose a network by hand.

Data is the second point. Think about how long you are away and how much you will use maps, messaging and browsing. A short city break needs far less than a month of remote work. The plan sizes below start at 1GB and go up to 50GB, so you can match the data to the trip rather than guess.

Validity matters too. A plan runs for a set number of days, from 7 to 180. Buy the duration that covers your whole trip, including the flight home. A plan that expires mid holiday leaves you without data when you need a map or a booking.

Hotspot is worth confirming. If you want to share data with a laptop or a travel companion, a plan that supports hotspot keeps you working. All Slashtel Greece plans are data only, so tethering is part of how you use them.

Finally, install before you fly. Adding the eSIM at home, on reliable wifi, avoids a rush at the airport and means you can switch it on the moment you land. The install guide at /guides/install-esim-iphone-android walks through the steps.

Plans and prices for Greece

Slashtel sells Greece plans in sizes from 1GB to 50GB, with durations of 7, 15, 30 or 180 days, and the price you see is the live price for that plan.

Each plan pairs a data amount with a validity period. Choose the combination that fits your trip. The table shows the starting prices for each size:

Longer durations are available up to 180 days for travellers who stay for a season or work remotely. Prices are shown in US dollars and update live on the site.

Networks and coverage in Greece

Your Greece eSIM connects to Wind, Vodafone and Cosmote, and the network is chosen automatically, so you do not need to change settings as you travel.

Those three operators run the mobile networks across Greece. Athens and the mainland have broad coverage, and the popular islands are served as well. Because your phone selects the network automatically, it can move to whichever signal is available where you are. You do not need to pick an operator or enter manual settings.

5G is available on the Greek networks, and your plan supports it where your phone and the local network allow. Actual speeds depend on where you are, the time of day and how busy the network is. We do not quote speeds because they change from street to street.

On ferries and in remote coves, signal can drop, as it does on any network. Download offline maps before a crossing and keep your bookings saved on your phone. That way a gap in coverage does not disrupt the day.

How much data you need

Match the data to the length and style of your trip: a short city break needs a small plan, while a long stay with hotspot use needs a larger one.

Use these starting points from the Slashtel range:

• One week: 1GB for 7 days, enough for maps, messages and light browsing.
• Two weeks: 2GB for 15 days, for a relaxed island hopping route with regular use.
• One month: 3GB for 30 days, for a longer stay where you mostly use wifi in hotels.

If you plan to use your phone as a hotspot, stream video or work remotely, move up to 5GB, 10GB, 20GB or 50GB. Island hopping often means less reliable hotel wifi, so a little extra data is useful for planning ferries, checking bookings and keeping in touch.

Install it before you fly

Install the eSIM at home on wifi, label it clearly, and switch it on when you land in Greece.

Buying and installing before departure removes the stress of setting up mobile data in a foreign airport. Follow the steps for your phone at /guides/install-esim-iphone-android. If you are unsure whether your handset supports eSIM, check /guides/is-my-phone-esim-compatible before you buy.

Give the eSIM a clear label such as Greece so you can tell it apart from your home SIM in settings. Keep your home SIM in the phone for calls and bank codes. When you arrive, turn on the Greece eSIM for mobile data and leave your home line active for incoming texts.

Calls, texts and your home number

The Greece eSIM is data only, with no local number and no calls or SMS, but WhatsApp and FaceTime calls work over the data connection.

Because there is no local number, you cannot make ordinary phone calls or send texts with the eSIM. Messaging apps that use data, such as WhatsApp, work normally, including voice and video calls. That covers most of what travellers need for restaurants, taxis and staying in touch.

Keep your home SIM in the phone for calls and bank codes. Many banks send verification texts to your usual number, so leaving that line active means you can still receive them. Check your home operator's roaming terms before you travel so you know what those incoming texts cost.

Questions travellers ask about Greece

The most common questions are about data only use, messaging apps, hotspot, when the plan starts, topping up and phone compatibility.

The answers below cover those points. If you need more detail on setup, the install guide and compatibility guide are linked above.

Greece is a popular destination for city breaks and island hopping, and a data only eSIM keeps you connected without changing your home number. Plan sizes from 1GB to 50GB and durations from 7 to 180 days cover most trips, and the three Greek networks give you automatic connection as you move between Athens and the islands.
