SIM Cards
Before traveling to Greece in 2026, it helps to know which SIM cards offer the best coverage, data value, and easy activation. Local providers are reliable, but plans and registration steps vary. This guide breaks down the best SIM card options for Greece and how to activate them once you arrive.
Picking the right SIM card in Greece depends on the kind of trip you’re taking, so I compared plans by price, data limits, validity, and coverage, as well as where it’s easiest to buy one, whether at the airport or in city stores. I focused on prepaid options that actually make sense for travelers, covering the basics like maps, messaging, and everyday browsing.
Quick pick: the best SIM card for Greece is Cosmote, thanks to its wider coverage and reliable speeds across both the mainland and islands. Local SIM cards are usually cheaper than eSIMs, but they can be harder to get, since you’ll need your passport, a store visit, and some setup time before you’re connected.

To help you compare the options quickly, here is a table of the best local SIM cards in Greece, including prices, data allowances, coverage, and where to buy them.
| Provider | Price (from) | Data | Validity | Network coverage in Greece | Where to buy | Best for |
| Cosmote | €14.00 ($16.60) | 15 GB | 30 days | Excellent, widest coverage across mainland and islands | Airport stores, city shops, kiosks | Travelers who want the fastest speeds and widest coverage, especially on islands or rural areas |
| Vodafone Greece | €20.00 ($23.73) | 50 GB | 14 days | Very good in cities and many islands | Airport stores, Vodafone shops, kiosks | Tourists who need reliable data for city use and moderate streaming without spending too much |
| Nova | €10.00 ($11.86) | 10 GB | 30 days | Good in cities and tourist areas | City shops and kiosks | Budget travelers who just need basic data for maps, messaging, and casual browsing |
When picking a SIM card in Greece, I always think about where I’ll actually be using it. Airport kiosks and city shops are easy to grab a SIM from, but they tend to be a bit more expensive. I usually go with Vodafone if I know I’ll be streaming Spotify or relying on Google Maps, but if I’m heading to islands or rural areas, Cosmote is my go-to for reliable coverage.
I also pay attention to how much data I really need and how long it lasts. On short trips, a 20–30 day plan is usually enough for me, but for longer stays I like to grab a bigger bundle. I always check if calling and SMS are included too, since having everything in one plan makes life much easier while traveling.
Cosmote, Vodafone Greece, and Nova are the top local SIM options for travelers because they offer reliable coverage, good value, and prepaid plans that are easy to set up. I also check their data roaming, which is really useful if I cross borders or want to use my SIM in nearby countries.
Prices and bundles can change, so I make it a habit to confirm the details either in-store or on the official websites before buying. That way, I know I’m picking a plan with enough data, the right validity, and coverage I can trust throughout my trip.
Cosmote is Greece’s largest mobile network, known for its excellent coverage across the mainland and islands. I find it reliable even in rural areas and on smaller islands, making it a top choice if you want consistent service throughout your trip. It’s especially good for travelers who plan to explore beyond the major cities.
| Duration | Data | Price | Note |
| 30 days | 15 GB | €14.00 ($16.60) | Good for light city use and moderate data needs |
| 30 days | 30 GB | €20.00 ($23.73) | Ideal for streaming, maps, and everyday browsing |
| 30 days | 60 GB | €31.00 ($36.76) | Best for heavy data users or sharing with multiple devices |
How to activate: Pick up a Cosmote SIM at the airport or in a city store, show your passport to register it, insert it into your phone, and follow the instructions to activate your chosen data bundle. You can also manage your balance and top up through Cosmote’s official app.
Quick verdict: Cosmote is great for travelers who want coverage you can rely on, even on islands and in rural areas. The trade-off is that it’s slightly more expensive than city-focused carriers, but you get peace of mind knowing your connection will work almost everywhere.
Vodafone Greece is a major carrier with very good coverage in cities and popular tourist areas. I usually pick it when I know I’ll spend most of my time in Athens, Thessaloniki, or other urban spots, because it handles streaming and navigation well. It’s a solid choice for travelers who want a balance of data and price.
| Duration | Data | Price | Note |
| 14 days | 50 GB | €14.00 ($16.60) | Short-term plan with high data allowance for busy travelers |
| 28 days | 30 GB | €35.00 ($41.51) | Balanced plan for longer stays with reliable coverage |
How to activate: Pick up a Vodafone SIM at the airport or a Vodafone store, show your passport for registration, insert it into your phone, and activate your chosen plan. You can manage your data and top-ups via the My Vodafone app.
Quick verdict: Vodafone is great for travelers spending most of their time in cities who need reliable data without overspending. The trade-off is slightly smaller coverage outside urban areas compared to Cosmote.
Nova is a smaller provider that focuses on basic prepaid plans for city and tourist areas. I usually choose it when I only need data for maps, messaging, or light browsing. It’s a simple option if you want a SIM that’s easy to set up and won’t break the bank.
| Duration | Data | Price | Note |
| 30 days | 10 GB | €10.00 ($11.86) | Budget-friendly, good for basic browsing and messaging |
| 60 days | 15 GB | €15.00 ($17.79) | Longer validity for slow data users or short trips spread out |
| 60 days | 30 GB | €25.00 ($29.65) | Good option if you want more data without paying for a premium plan |
How to activate: Buy a Nova SIM at city kiosks or stores, show your passport, insert it into your phone, and follow the instructions to activate your plan. You can also top up through the Nova website.
Quick verdict: Nova is ideal if you just need basic data and want the cheapest option for your trip. The trade-off is limited coverage outside cities and major tourist areas.
