Your eSIM roams onto Greece's own operators. These are the networks and the frequencies they run — check your phone supports them before you travel.

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.
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.
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.
Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.
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.
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.
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.
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.
Greece offers a deep mix of ancient history and natural beauty. These are the sites most worth your time.
Greek food is simple, fresh, and full of flavor. These dishes are widely available and worth seeking out.
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.
Pack light and smart for Greece’s Mediterranean climate. You will walk on uneven stone streets and spend time in the sun.
