Which Greece eSIM plan fits your trip?

Choose your Greece eSIM by matching the allowance and validity period to your trip, then compare the selected product details with the local network, band and speed references already shown on this page.

Start with the length of your stay, then allow for navigation, messaging, streaming and work use. Each option below is a plan size that is currently available for this destination.

Short trip

1 GB / 7 days

Best for: A short visit with maps, messages and occasional browsing.

This option pairs the 1 GB allowance with a stated validity period of 7 days.

Usage tip: Save maps before longer journeys and use Wi-Fi for large downloads.

Two-week trip

3 GB / 15 days

Best for: A stay of around two weeks with regular navigation and messaging.

The 3 GB allowance remains available across a stated validity period of 15 days.

Usage tip: Keep automatic app updates and cloud backups on Wi-Fi.

Longer or higher use

10 GB or more / 30 days

Coverage in Greece

Mountainous interior and many small islands have no service or 2G/3G-only coverage. B20 (800 MHz) and B28 (700 MHz) are widely used for rural LTE coverage; some foreign phones lack B28.

How to check mobile coverage in Greece

The Greece mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.

Accommodation and daily stops

Check your accommodation and the places you expect to visit in Greece. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.

Journeys between stops

Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.

Borders and onward travel

Check the selected product scope for every country on your itinerary. Your Greece plan and a regional plan may have different included destinations and validity periods.

Phone compatibility in Greece

Compare your phone with 4G bands B1, B3, B7, B20, B28 and 5G bands n1, n3, n28, n78 in the existing Greece network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.

Set up the Greece eSIM for your trip

Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.

When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.

  1. Confirm that your phone is unlocked and supports eSIM before purchase.
  2. Save the QR code or manual installation details somewhere you can reach without mobile data.
  3. Use reliable Wi-Fi to install the profile at the time recommended in the product instructions.
  4. When you are ready to use it, select the travel eSIM for cellular data and apply the stated roaming and APN settings.
  5. Keep roaming disabled on your home line if you want to avoid using its travel data.

Greece travel guide

Enjoy Greece Like a Local

Greece rewards slow travel. Skip the rush between islands and allow at least three nights in each place you visit. In Athens, start your day early to see the Acropolis before the heat and crowds arrive. Afternoon is best for a long lunch in a shady taverna in Plaka.

On Santorini, avoid the cruise-ship surge by exploring the caldera trails in the late afternoon. Stay in a smaller village like Pyrgos rather than Oia or Fira for a quieter experience. Greek hospitality means you are welcome to linger at a table after a meal. Order a coffee or a glass of ouzo and watch the evening pass. Tipping is appreciated but not expected. A few euros left on the table is a kind gesture.

Top Attractions in Greece

Greece offers a deep mix of ancient history and natural beauty. These are the sites most worth your time.

  • Acropolis and Parthenon - Athens’ defining landmark. Go at opening time or late afternoon to avoid the worst crowds. A combined ticket for several archaeological sites saves money.
  • Santorini - Famous for its blue-domed churches and caldera views. The island is most enjoyable in the shoulder months of May and September.
  • Delphi Archaeological Site - Home of the ancient Oracle. The setting on Mount Parnassus is dramatic. Allow a full morning to explore the ruins and museum.
  • Meteora Monasteries - Six monasteries perched on towering rock pillars. Wear sturdy shoes for the steep paths. Check opening days online before you go.
  • Mykonos and Crete - Mykonos for its Cycladic charm and nightlife; Crete for its varied landscapes, Minoan ruins, and hiking in the Samaria Gorge.

Essential Greek Foods to Try

Greek food is simple, fresh, and full of flavor. These dishes are widely available and worth seeking out.

  • Moussaka - Layers of eggplant, potato, and spiced meat topped with béchamel. Hearty and satisfying. Look for a version that tastes homemade, not reheated.
  • Souvlaki - Grilled meat on a skewer or wrapped in pita with tomato, onion, and tzatziki. A quick, cheap meal that is hard to get wrong.
  • Greek Salad (Horiatiki) - Fresh tomatoes, cucumber, onion, olives, and feta. Dress with oregano and olive oil. The quality depends entirely on the ripeness of the produce.
  • Spanakopita - Flaky phyllo pie filled with spinach and feta. Best eaten warm from a bakery.
  • Baklava - Layers of phyllo, nuts, and syrup. Very sweet. A small piece is enough.

Best Time to Visit Greece

Greece has a Mediterranean climate with hot, dry summers and mild, wet winters. The best travel windows are spring and autumn.

April to June offers pleasant temperatures, blooming wildflowers, and smaller crowds. The sea is cool but swimmable by late May. September and October are similarly comfortable. The water stays warm through early October, and the summer crowds have thinned.

July and August are peak season. Temperatures often exceed 35°C in Athens and the islands. Prices are high, and popular sites are packed. If you travel then, book accommodation and ferry tickets well in advance and plan outdoor activities for early morning or evening.

Winter (November to March) is quiet. Many island hotels and restaurants close. Athens and Thessaloniki remain lively, and you will find lower prices and a more local atmosphere.

Packing Essentials for Greece

Pack light and smart for Greece’s Mediterranean climate. You will walk on uneven stone streets and spend time in the sun.

  • High-SPF Sunscreen and Hat - The sun is strong, especially on islands and at archaeological sites. Reapply often.
  • Lightweight, Breathable Clothing - Linen and cotton are ideal. Dark colors hide dust and sweat. A light long-sleeved shirt protects from sun and mosquitoes.
  • Comfortable Walking Shoes - Many streets are cobbled or unpaved. Sandals with good grip work, but sturdy sneakers are better for ruins and hills.
  • Swimsuit and Beach Cover-Up - Beaches range from organized to rocky coves. A cover-up is polite when entering a taverna or church after swimming.
  • Reusable Water Bottle - Tap water is safe in most cities. On some islands it is not; buy bottled water there. A reusable bottle cuts waste and cost.

Common Questions

The details worth knowing about your Greece eSIM

No. Many small islands and mountainous interior areas have no service or only 2G/3G coverage. Your eSIM will work on the major islands and mainland cities, but you may lose data connectivity on remote islands. Check coverage maps for your specific itinerary.

Yes, you may. Cosmote, Vodafone GR and NOVA all use B28 (700 MHz) for rural 4G coverage. Without it, your phone will rely on higher bands with shorter range, so you could lose signal in less populated areas. B20 (800 MHz) helps too, but B28 is critical for deep rural reach.

It depends on your eSIM provider. The three main networks are Cosmote, Vodafone GR and NOVA. All three support 4G on bands B1, B3, B7, B20 and B28, and 5G on n28 and n78. Your eSIM may roam across them or lock to one; check your provider’s policy.

This page is for Greece only. Coverage of neighboring countries like Turkey, Albania, North Macedonia or Bulgaria depends on your eSIM plan. Some eSIMs include regional data, but this FAQ does not cover that. Check your plan’s country list before traveling.

Local Greek prepaid SIMs require ID registration by law, but eSIMs purchased abroad from international providers typically do not require Greek ID. However, some eSIMs may ask for your passport during purchase. Confirm with your eSIM provider before you travel.

Compare 1 GB / 7 days, 3 GB / 15 days and 10 GB or more / 30 days. Use the shorter profiles for lighter maps and messaging use, then compare the larger allowance for streaming, video calls or work apps.

The start rule is product-specific. Review the selected plan details before installing it so you know whether any action is required before arrival.

Save the QR code, manual installation details, APN guidance and the support instructions supplied with the selected plan.
