Staying connected in Greece

Greece splits neatly into the mainland, which is well covered along the motorways and around Athens and Thessaloniki, and the islands, which vary enormously. The larger and more visited islands are fine. The smaller Cyclades and the more remote Dodecanese can drop to a single bar away from the main town and the port. A Halo eSIM installs before you fly and starts counting on its first connection after you arrive. Ferry crossings usually hold a signal near the coast and lose it in open water, which matters because ferry schedules change and you will want to check them. Download offline maps and your ferry bookings before you sail. Mountain roads on Crete and in the Peloponnese also have real gaps, so do not rely on live navigation there.

How much data you'll need

Four to six GB for a week. Island hopping pushes it up, because you will check ferry times, maps and accommodation constantly and small-island Wi-Fi is often too slow to be worth waiting for. A stay in one place on a larger island is lighter, at three to four GB.

5G

Our Greece plans run on networks carrying 5G, which is established in Athens and Thessaloniki and less consistent on the smaller islands.

Questions? We've got answers.

  • Will I have signal on the ferries between islands?

    Near the coast and around the ports, usually yes. In open water between islands the signal often disappears entirely, and crossings in the Cyclades can be several hours. Download your onward tickets, accommodation address and an offline map before you board.

  • Is coverage reliable on the smaller islands?

    It varies a great deal. The main town and the port on any inhabited island will have coverage. Beaches, hiking paths and the far side of a small island frequently do not. Treat live navigation as unavailable once you leave the main settlement and download maps in advance.

  • Can I call and send SMS on my Greece eSIM?

    Halo eSIMs are exclusively data-only eSIMs. While you can engage in voice calls and messaging through WhatsApp, Facetime, and other widely used VOIP apps, traditional phone calls and SMS are not supported.

  • Is my device compatible with this Greece eSIM?

    Most phones from 2018 onwards support eSIM, including iPhone XR and XS and newer, Pixel 3 and newer, Galaxy S20 and newer. If it's a reasonably recent phone, you're probably fine. Check our device compatibility page if you want to be sure.

  • When should I set up my Greece eSIM?

    Before you leave, while you're still on Wi-Fi. Your plan only starts counting when you first connect to a network at your destination, so there's no cost to installing early. Greece plans run from 1 to 45 days from that first connection. One less thing to sort at the airport.

  • Which networks does my Greece eSIM use?

    Each plan lists its own networks and speed policy under Plan details on this page. Which networks a plan uses is set by our network partners and can change without notice, so we show them per plan rather than for the destination as a whole. Your device finds and connects to a supported network on its own when you arrive.

  • Can I top up my Greece eSIM?

    Yes, on the fixed-data plans. Running low? Purchase another plan for the same destination from your order page. The new data gets added to your existing eSIM. No reinstall needed. Top-ups are not available on the Unlimited (daily) plans. To keep using data after an Unlimited plan ends, buy a new plan.

  • Can I hotspot with my Greece eSIM?

    Hotspot availability depends on the plan. Halo adds no separate hotspot cap and does not meter hotspot data differently, so on plans that support it you can share your connection with a laptop, tablet or travel companion where the local network allows. Hotspot is provided by the network operator in Greece rather than by Halo, so it is not something we can guarantee on every plan.
