Best eSIM for Greece: How We Picked

To find the best eSIM for Greece, we evaluated providers based on several key criteria to ensure a reliable and valuable experience for travelers:

• Network speed & coverage across mainland Greece and its many islands.
  
• Price per GB and overall value for money.
  
• Transparency of data usage and fair policy details.
  
• Hotspot support for sharing your connection with other devices.

Greece eSIM Coverage & Speeds: What to Expect

You can expect strong mobile networks in Greece, especially in cities and on major islands. In Athens, Thessaloniki, and islands like Mykonos and Santorini, coverage is excellent with widespread 4G/LTE and growing Greece 5G availability from local carriers like Cosmote, Vodafone, and Wind. While Greece mobile network speeds are generally fast in these areas, speeds can lower to 3G in more remote mountainous or rural locations. Most travel eSIMs partner with these major networks to offer reliable service.

How to Choose the Best eSIM for Greece

Selecting the right eSIM depends on your travel style. Consider the length of your stay and your data consumption—are you a light user checking maps and messages, or do you stream videos? Determine if you need hotspot functionality to share data with a laptop or tablet. If you're multi-country traveling, look for a regional Europe plan, which can be a great value for trips like a combined best eSIM for Italy and Greece or a best eSIM for Greece and Turkey itinerary. Finally, balance all these needs with your budget.

3. Nomad Greece eSIM — Good for Medium-Data Users

Nomad is an excellent choice for travelers with moderate data needs. It provides clear, mid-range plans with straightforward pricing and a well-reviewed app experience. Its plan durations are often structured in weekly or monthly increments, offering less flexibility for very short trips.

It provides mid-range pricing for medium-data plans (like 3GB or 5GB for 30 days), which is sufficient for regular social media use, email, and some mapping. Users often praise its simple, clean app interface for managing data. Its plan durations can be less flexible than some competitors, often structured around weekly or monthly options. It's a great "set-and-forget" option for the average tourist.

4. Holafly Greece eSIM — Best for Unlimited Data Needs

For travelers who don't want to think about data limits, Holafly is the standout choice for the best eSIM for Greece unlimited data. Its main advantage is offering truly unlimited data plans. The trade-off is that most unlimited plans do not support personal hotspot, and they come at a higher price point.

Its primary advantage is offering truly unlimited data plans, freeing you from constantly monitoring your balance. This is perfect for remote workers, content creators, or anyone who streams frequently. The main trade-off is that most of its unlimited plans do not support personal hotspot/tethering, or allow only a small daily amount (e.g., 500MB). These plans also come at a higher price point than limited-data options.

5. Orange Holiday Europe — Best for People Who Need Calls + SMS

If you need to make traditional phone calls, the Orange Holiday Europe eSIM is a unique all-in-one solution. This plan includes a European call/SMS allowance alongside a data package. It has fixed validity periods and is priced higher than data-only plans.

This plan uniquely includes a generous allowance of call minutes and SMS texts to European numbers, alongside a substantial data package. It's a convenient all-in-one solution. The plan typically has a fixed 14-day or 30-day validity, so it's less flexible for very short trips and can be slightly more expensive if you only need data.

6. Cosmote Greece eSIM — Local Carrier Option

For those preferring a local operator, Cosmote eSIM provides access to Greece's largest network. The advantage is excellent native coverage, but activation requires an in-store visit with passport registration, which is inconvenient for most tourists.

The key advantage is potentially getting the best possible native network coverage and speeds, as Cosmote boasts 99% population coverage. The significant downside for tourists is the activation process: you must visit a physical Cosmote or partner store (like at the airport), present your passport for ID verification, and choose from local prepaid plans. This can be time-consuming and is not ideal for short visits seeking instant connectivity.

Tips for Using eSIM in Greece

• Download Offline Maps: Use Google Maps or Maps.me to download maps for your destinations over Wi-Fi to save data.

Best Alternatives to Greece eSIM (If Your Phone Isn't Compatible)

If your phone doesn't support eSIM, you have three main alternatives:

• Pocket WiFi: Rent a portable Wi-Fi device. Good for groups, but requires daily charging, carrying an extra device, and often a deposit.
  
• Local SIM Card: Buy a physical SIM upon arrival. It can be cheap but requires finding a store, registering with your passport, and swapping out your home SIM.
  
• Roaming Package: Purchase an international package from your home carrier. This is the most convenient but almost always the most expensive option.
